Yes because of you find the gcf for 9 and 15, the answer would be 3 so the asnwer is still odd.
The radius is always half of the diameter so it would be 20 inches
Answer:
28.26
Step-by-step explanation:
area of a circle is (pi)(r)^2
radius is half of the diameter
6/2=3
3 feet is the radius
a= 3.14 (3)^2
=3.14 x 9
= 28.26 feet
Answer:
0.25D^2 π in^2.
Step-by-step explanation:
The cross section is a circle of diameter D inches, so its radius is 0.5D inches.
The area of cross section is πr^2
= (0.5D)^2 π
= 0.25D^2 π in^2.
