A volume of a coin is 113.04 mm2 what is the approximate of a sphere that has the same height and a circular base with the same
tia_tia [17]

We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.

We know that volume of cone is \frac{1}{3}\pi r^2\cdot h.

The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:

h=2r

Upon substituting h=2r in volume of cone, we will get:

V=\frac{1}{3}\pi r^2\cdot 2r

V=\frac{2}{3}\pi r^3

We know that volume of sphere is V=\frac{4}{3}\pi r^3.

Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.

V=2(\frac{2}{3}\pi r^3)

Since \frac{2}{3}\pi r^3=113.04, so volume of sphere would be:

V=2(113.04)

V=226.08

Therefore, volume of sphere would be 226.08 cubic mm.

Answer:

20cm

Step-by-step explanation:

Let s = the length of the base

Let 4s = the length of the height

V = BH       Since the base is a square, B = s2

V = s2 H

500 = s2(4s)

125 = s3

s = 5 cm

4s = 20 cm - the height
