WILL MARK BRAINLIST FOR THE CORRECT ANSWER!! The figure shown is formed by a square of area 4 and a semicircle. Find the perimeter of the figure.
A) π + 6
B) π + 8
C) 2π + 4
D) 2π + 6

answer is A

Step-by-step explanation:

3*2=6

2pi/2=pi

e) none of the above because the measure of angle cba is 101°

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
