The ratio of the circumference what is 2pir so for A. is right circumference and for B. is right diameter what is 2r because the ratio of circumference and diameter is equal 2pi*r/2r = pi so 3,14
so C/D = 2pir/2r = pi so 3,14
hope this will help you

Answer:
23
Step-by-step explanation:
This equation can be derived from the question
let a represent the initial number Gus started with
{[(a x 8) - 12] / 4 } + 7 = 50
subtract 7 from both sides of the equation
[(a x 8) - 12] / 4 } = 43
Multiply both sides of the equation by 4
(a x 8) - 12] = 172
Add 12 to both sides
8a =184
Divide both sides by 8
a = 23.
The answer is c to the fourth power.
(12)(20)= 240
The answer is going to be B. 240 sq ft
