Answer:
50.2 in^2
Step-by-step explanation:
Using the Formula
A=πr2
d=2r
Solving for A
A= 1/4 π d^2 = 1/4*π*8^2 = 50.26548
=50.2in^2
Answer:
C, D, F
Step-by-step explanation:
She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.
That means she walked 12 miles plus 1/4 of 12 miles.
She walked
12 + 1/4 * 12
You can factor out 12 from the expression above, and write it as
12(1 + 1/4)
Now you can do the addition in parentheses.
12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)
Answer:
C, D, F
