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

Respuesta :

Answer:

C

Step-by-step explanation:

Radius: 12 / 2 = 6 m

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

Answer:

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
