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.
