Question

If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answer 1

13.14

Explanation:

v= 1/3 pi r^2 h

45 = 1/3 (3.14) (4) h

45 = 1/3 (12.56) h

45 = 1/3 12.56/ 4 = 4 h/4

h = 3.14

45 = 1/3 (12.56) (3.14)

45 = 1/3 (39.44)

45 = 39.44/3 = 13.14

Answer 2

3.58

Explanation:

45cm3= 2 squared x height x 3.14

So you take 45 and divide it by 2 squared which is 4 and 3.14. Then you would get 3.582 and round it to 3.58
