How much fencing is needed to enclose a circular pond with diameter 12.5 feet?
A.
37.5 feet **?
B.
19.625 feet
C.
78.5 feet
D.
39.25 feet
Using 3.14 as Pi
12.5 x 3.14 = 39.25
D is the correct answer
A is wrong.
Circumference = pi * diameter
C= pi d
C= 3.14* 12.5
therefore you get D 39.25 hope that helped!
18. Find the area of a trapezoid whose base1= 8 in. and
base2= 10 in with the height of 7 inches.
Its D it shows that in the problem.
I chose the answer is D.
I'm not quite sure what the answer is.
I kind of guessed, but I'm really just looking for something that tells me what to multiply.
