Question

Pls help I can't figure out the problem and I need help it worth a lot of points in my grade

Answer 1

Perimeter 18.42

Area 20.13

Explanation:

Perimeter:

This is the distance around the figure.

The distance around the triangle is 9.

The distance around the 1/2 circle

c= 2
`\pi`r

c [2(3.14)(3)]/2

c = 9.42

9.42 + 9 = 18.42

Area:

triangle

a = 1/2(bh)

a - 1/2 (3)(4)

a = 6

circle

a = 1/2(
`\pi r^(2)`)

a = 1/2(3.14)(9)

a = 14.13

6 + 14.13 = 20.13
