Answer:
C = 22π; A = 121π.
Step-by-step explanation:
To find the circumference of a circle, you do pi times the diameter. That would be 22pi.
To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.
So, C = 22pi; A = 121pi .
Hope this helps!
Answer:
C = 22π, A = 121π
Step-by-step explanation:
formula for circumference is C=2πr. C= 2π(11) therefore C=22π
formula for are is A=πr² therefore A=π(11)²= 121π
