The figure is made up of two shapes, a semicircle and a rectangle.

what is the exact perimeter of the figure?

a. 4 pi + 26 in.

b. 8 pi + 34 in.

c. 4 pi + 34 in.

d. 8 pi + 72 in.

Option A

Step-by-step explanation:

we know that

The perimeter of the figure is equivalent to the perimeter of a rectangle plus the perimeter of semicircle minus the length side of inches

step 1

Find the perimeter of rectangle

the perimeter of rectangle is equal to

we have

substitute

step 2

Find the circumference of semicircle

the of circumference of semicircle is equal to

we have

substitute

step 3

Find the perimeter of the figure

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
