Answer: B
Step-by-step explanation: A=πr2
The formula for calculating the area of a circle is A = πr2 where pi (π) equals 3.14 and the radius (r) is half the diameter.
You must times 5 by 5 because of exponents and then times it by pie
5 times 5 = 25
25 times pie is 78.5
Answer:
C
Step-by-step explanation:
The total circumference = 5*2 pi = 10pi
You are trying to find (360-44)/360 of the circumference, which simplifies to 79/90.
79/90 *10pi =
79pi/9, which is C
