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 3.1m2.

Step by step solution

01

Step 1. Given information.

A quarter circle with diameter 4 meters.

02

Step 2. Concept used.

Area of a quarter circle with radius r is given by A=蟺r24.

03

Step 3. Calculations.

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

A=蟺r24=3.14脳224=3.14脳44=3.14m2

Rounding off to the nearest tenth, we get,

A=3.1m2

Thus, the area of the quarter circle is 3.1m2.
