Question

2 find the total surface area of the solid hemisphere shown. (with an image of a hemisphere with radius 3 cm)

Explanation:

Step1: Recall the formula for the total surface area of a solid hemisphere

The total surface area \(A\) of a solid hemisphere is \(A = 3\pi r^{2}\), where \(r\) is the radius of the hemisphere.

Step2: Substitute the given radius into the formula

Given \(r = 3\space cm\). Substitute \(r = 3\) into \(A=3\pi r^{2}\).

Taking \(\pi\approx3.14\), we have \(A = 27\times3.14=84.78\space cm^{2}\)

Answer:

The total surface area of the solid hemisphere is \(84.78\space cm^{2}\)
