Question

This figure is made up of a triangle and a semicircle. What is the area of this figure? Use 3.14 for pi. Round only your final answer to the nearest tenth. Enter your answer, as a decimal, in the box

Answer 1

Area = 14.8 units²

Explanation:

Base of Triangle = 2 units

Height of Triangle = 5 units

Radius of the semi circle = 2.5 units

Now,

Triangle:

Area of triangle = 1/2(base*height)

Area = 1/2(2*5)

Area = 1/2(10)

Area = 5 units²

Semi-Circle:

Area of semi-circle = 1/2(πr²)

Area = 1/2(3.14)(2.5)²

Area = 1/2(3.14)(6.25)

Area = 9.8 units²

Area of the figure:

Area = 5 + 9.8

Area = 14.8 units²
