find the volume of the cone using the given formula

Answers

Answer 1

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.

There are 8 footballs in a store cupboard; one is yellow and the others are
white. A pupil takes 2 footballs out of the cupboard at random. What is the
probability that one of them is the yellow ball?

Answers

⚾️= white football (. I know It’s not)
= Yellow football( same thing)

⚾️⚾️⚾️⚾️⚾️⚾️⚾️
We could re-arrange this many ways max 8 but with white each one has 8
Soo 8•7 equals 56
There is a chance in 56 times they only get the yellow ball 8 times but the white one would be chosen most of the times.

Hope this helps you.

A baker decorates 42 cupcakes in 30 minutes. She decorates cupcakes at a constant rate.

Answers

Since the baker can bake 42 cupcakes in 30 minutes, and we need to find how many she can decorate in 1 min, we divide the 30 min by 30 to get 1 min, and divide 42 by 30 as well since it is a constant rate and we need to keep it proportional. 42/30 is 1.4, so she can decorate 1.4 cupcakes in 1 min. Hope this helps!

Each bag must have the same number of toy cars in it.

Each bag must have the same number of toy helicopter in it.

All bags must have the same number of toys in it.

a) How many bags will contain toy cars?

b) How many bags will contain toy helicopters?

Think of highest common factor of 56 and 77

Both numbers are divisible by 1, 2, and 7 and the highest common factor is 7

56 ÷ 7 = 8

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281
