Caitlin drew a circle and labeled the circle S. The diameter of Caitlin’s circle is 12 m. Which of the following best represents the area of Caitlin’s circle? A. 452 m^2
B. 38 m^2
C. 113 m^2
D. 75 m^2

C

Step-by-step explanation:

Radius: 12 / 2 = 6 m

Area: 6^2 x pi = 113 m^2

c

Step-by-step explanation:

area = π · r²

to change the diameter to radius you just divide by 2

12/2=6 so the radius is 6

then we just plug 6 into r for the circle are formula

6²=36

36x3.14=113.04 so her best answer choice is c

answer:

sometimes

*i think

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
