Question

Using the shape below, find the area of the shaded region. Round your answers to the nearest tenth (1 decimal place) if needed. Use 3.14 for TT.

r = 9.7
type your answer

Answer 1

Solution given:

base for triangle=2r=2*9.7=19.4

height [h]=9.7

area of triangle=½base *height=½(19.4×9.7)=94.09units²

area of circle=πr²=3.14×9.7²=295.4456units²

Now

Area of shaded region=295.4456-94.09=201.3536units²

Answer 2

• 201.4

Explanation:

The triangle's base is the diameter and height is the radius of circle.

The shaded area is:

• A = πr² - 1/2bh
• A = 3.14*9.7² - 1/2(2*9.7)(9.7) = 201.4
