Chapter 1: Q8. (page 28)

Find the area of each figure. Round to the nearest tenth if necessary.
A quarter-circle with a diameter of 4 meters

Short Answer

Expert verified

The area of the circle is $3.1 m^{2}$ .

Step by step solution

Step 1. Given information.

A quarter circle with diameter 4 meters.

Step 2. Concept used.

Area of a quarter circle with radius r is given by $A = \frac{π r^{2}}{4}$ .

Step 3. Calculations.

Since the radius is half of the diameter, so, the radius of the quarter circle is 2 meters.

$A = \frac{π r^{2}}{4} = \frac{3.14 \times 2^{2}}{4} = \frac{3.14 \times 4}{4} = 3.14 m^{2}$

Rounding off to the nearest tenth, we get,

$A = 3.1 m^{2}$

Thus, the area of the quarter circle is $3.1 m^{2}$ .
