Question

A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?

Answer 1

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

$V = \pi {r}^{2}h$

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

$351.68 = 3.14 \times {4}^{2} \times h$

$351.68 = 50.24h$

Divide both sides by 50.24 to get:

$h = \frac{351.68}{50.24}$

h=7 inches

Therefore the height of the jar is 7 inches
