Answer 6

@AnitaS.

Answer 7

V=hpir^2
d/2=r
3.5/2=r and 5=h
r=1.75
V=5*3.14*1.75^2=your answer

Answer 8

ok let me solve that... give me a sec.

Answer 9

i got 48.08!

A beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your answer to the nearest hundredth.

314.00 cubic inches
452.23 cubic inches
500.75 cubic inches
523.33 cubic inches

Answer 11

wait i don't get 5^3.14? is that correct

Answer 12

or is it 5^3 * 4/3.. @smartnerd1111

Answer 13

oops The formula for the volume a a sphere is 4/3 x 3.14 x radius^3, so that would be 4/3 x 3.14 x 5^3. 4/3 * 3.14 * 125 = answer

Answer 14

so i solve 4/3 * 3.14 * 125 to get the answer?

Answer 15

yes

Answer 16

ok... @smartnerd1111

Answer 19

A glass vase is shaped like a cylinder and has a radius of 2.5 inches. The vase holds 170 cubic inches of water. How tall is the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

8.66 inches
9.78 inches
10.35 inches
12.50 inches

Answer 20

@smartnerd1111 ??

Answer 21

im coming

Answer 22

ok..

Answer 23

Okay, the volume of a cylinder is pi r^2 h, so to find the height, you just need to divide the volume by the radius squared and then by 3.14, our approximation of pi.
170 / 2.5^2 = 170 / 6.25 = 27.2
27.2 / 3.14 = 8.662420582...
Rounds to 8.66

Answer 24

ok next!
