Chapter 1: Q9. (page 28)

Find the area of each figure. Round to the nearest tenth if necessary.
A semi-circle with a radius of 3 inches.

Short Answer

Expert verified

The area of the semi-circle is $14.1 {in}^{2}$ .

Step by step solution

Step 1. Given information.

A semi-circle with radius of 3 inches.

Step 2. Concept used.

Area of a semi-circle with radius r is given by $A = \frac{π r^{2}}{2}$ .

Step 3. Calculations.

$A = \frac{π r^{2}}{2} = \frac{3.14 \times 3^{2}}{2} = \frac{3.14 \times 9}{2} = 14.13 in .^{2}$

Rounding off to the nearest tenth, we get,

$A = 14.1 in .^{2}$

Thus, the area of the semi-circle is $14.1 in .^{2}$ .
