The diameter of the base of a cylinder cookies is 8 inches. the volume of the cookie jar is 160 cubic inches. what is the height of the cookie jar?

Hello!

To calculate the height of the cookie jar, we must use this formula.

FORMULA FOR HEIGHT:

H = V ÷ 3.14 × r × r

First, let's fine the radius. The radius of a circle is always half of the diameter. This means we must divide the diameter by 2.

r = d ÷ 2

r = 8 ÷ 2

r = 4 inches

The radius is 4 inches. Now, let's use the formula and find that height!

FORMULA:

H = V ÷ 3.14 × r × r

V = 160 cubic inches

Pi = 3.14

r = 4 inches

h = ?

First, square the radius.

160 = (3.14(4 × 4))h

160 = (3.14 (16))h

Now multiply that by pi.

160 = 50.24h

Finally, divide this by the volume:

160 ÷ 50.24 = 3.18 (Repeating Decimal)

Just round the repeating decimal to 3.2

A N S W E R:

The height of the cookie jar is about 3.2 inches.
