Circle P has a circumference of approximately 75 inches.
What is the approximate length of the radius, r? Use 3.14
for y. Round to the nearest inch,
12 inches
D24 inches
38 inches
46 inches

12 in

Step-by-step explanation:

C=2pi *r

75/2(3.14)=r

r=75/6.28

~11.94~12 inches

if my answer helps please mark as brainliest

12 in

Step-by-step explanation:

Circumference:

C = 2πr

75 = 2(3.14)r

75 = 6.28r

r = 75/6.28

r = 11.95 ≈ 12

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
