Question

Find the area of this shape

Answer 1

a = 4pi

Explanation:

The formula of finding a area of a circle is "a = piR^2.

Replace the R with the radius which is 2 for this circle.

Answer 2

• Area of shape is 9.42 units²

Explanation:

From the picture we observe:

1. The shape is 3 quarters of circle as one quarter is excluded (note the right angle);

2. The radius of the circle is 2 units.

Use area formula of circle to find the area of given shape:

• A = πr², area of circle

• A = 3πr²/4 = 3*3.14*2²/4 = 9.42 units², area of shape
