Answer:

A)  B is greater

B) when C = 21, A = 5 and B = 15

C) A must be 0, 5, or 12 for C to be greater than B

Step-by-step explanation:

A)  when a = -3, c = -20 and b = 4(-3)-5 so B = -17

B) when c = 21, a = 5 and b = 4(5)-5 so B = 15

C) C is greater than B when a = 0, 5, and 12

when a = 0, b = 4(0)-5 or -5

when a = 5, b = 4(5)-5 or 15

when a = 12, b = 4(12)-5 or 43

tankabanditka [31]
Circumference = 2 \pi r

42/(2 \pi) = r
21/\pi = r

Area = \pi r²
         = \pi (21/\pi)²
         = 21²/\pi
         = 140.37
         ≈ 140.4
