Find the circumference and area of a circle with diameter 4 cm.
HELP ASAP PLS
Answers
Step-by-step explanation:
the formulas can be easily found on the internet.
remember, the diameter of a circle is 2 times the radius.
so, the radius of our circle here is 4/2 = 2 cm.
circumference :
2×pi×r = 2×3.14×2 = 12.56 cm
area :
pi×r² = 3.14×2² = 3.14×4 = 12.56 cm²
hey, your teacher gave you the circle, where the circumference and the area have the same quantity ! funny !
so, make double sure you use the correct unit dimensions (remember, a distance has only one dimension, an area has 2 dimensions, and a volume has 3 dimensions).

A medium pizza cheese pizza a papa johns costs $6.80 plus $0.90 for each topping. The cost of a medium cheese pizza at pizza hut is $7.30 plus $o.65 for each topping. How many toppings need to be added to a large cheese pizza from papa johns and pizza hut in order for the pizzas to cost the same, not including tax?
Answers
Answer:
I hope I answered your question!
Step-by-step explanation:
6.80+0.90x=7.30+0.65x (multiply by 100 on both sides)
680+90x=730+65x
50=25x
x=2
Therefore you need to add 2 toppings to each pizza to make them cost the same.
Annabelle measured her bedroom as 11 ft times 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply. there are 12 inches in every foot. the length and width will change by a factor of 1.2 times 10 superscript 1. the length and width will change by a factor of 1.2 times 10 superscript 0. the area will change by a factor of (1.2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 1.44 times 10 superscript 2 baseline = 144, since area is length times width. the area will change by a factor of 2 (1.2 times 10 superscript 1 baseline) = (2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 2.4 times 10 superscript 2 baseline = 240, since both the length and width increase by that factor.
Answers
There are 12 inches in every foot and the area will be increased by 144 factors.
We know that the feet and inches are the units of length. One foot is 12 inches.
The length and the breadth are given as 11 feet and 13 feet.
The area of the bedroom is 143 square feet.
We know that 1ft = 12 in
So, The length would become 11 feet to 132 inches.
The breadth would become 13 feet to 156 inches.
What is the formula for the rectangle?The area of the rectangle = length × Width
Therefore, the area of the rectangle = 132 × 156
Since area of the rectangle= 20592 in .sq
The area of the bedroom increased by 144 factors.

Answers
Answer:
210 x 21 = 4410 calories burned for 1 adult
4410 x 8 = 35280 calories burned for 8 adults
Step-by-step explanation:
First you figure out how much calories are burned total for 1 adult on a 21 hour bike ride with the information that you know of how much adults burn.
Next you multiply your answer by 8 to figure out the total of calories burned for all 8.
Step-by-step explanation:
35280 calories would be burnt.
I think it will help you.
210×21=4410

Is B the expression for the perimeter of the rectangle, in inches?
Answers
Answer:
A, C, D
Step-by-step explanation:
P = 2L + 2W
L = 5W - 2
P = 2(5W - 2) + 2W
P = 10W - 4 + 2W
P = 12W - 4
Answer choices A, C, and D = 12W - 4
I hope this helps!
that can be represented as 5w-2
the equation for perimeter is 2l+2w=p, where l is the length, w is the width, and p is the perimeter
so, plug in the equation we found into the length part of the perimeter equation and leave 2w the same
2(5w-2)+2w
that makes A correct
however, when you distribute the 2, the equation becomes 10w-4+2w
combine like terms to get 12w-4
that would make d also correct
in conclusion, a and d are the correct answers
hope that helps!!
