Question

To the nearest centimeter, find the surface area of a hemisphere with 15 inch diameter

Answer 1

Given:

The diameter of the hemisphere is 15 inches.

To find:

The surface area of a hemisphere.

Step-by-step explanation:

The radius of the hemisphere is

`r=(15)/(2)inches`

Using the formula of the surface area of a hemisphere,

`\begin{gathered} S.A=2\pi r^2 \\ =2*3.14*((15)/(2))^2 \\ =353.25 \\ \approx353square\text{ }inches \end{gathered}`

Final answer:

The surface area of the hemisphere is 353 square inches.
