1] The circumference=72π, thus the radius will be found as follows: C=2πr therefore radius r will be: 2πr=72ππ r=(72ππ)/(2π) r=36 hence: Area=πr²=π(36)²=1296π
2] Circumference= 32ππ, the radius will be: C=2πr 2πr=32π r=(32π)/2π r=16
3] Radius of circle P is 24 cm, radius of circle Q is 8 cm: Area of circle P is: A=πr²=π×24²=576π Area of circle Q is: A=πr^2=π×8²=64π therefore comparing the two areas: (576π)/(64π)=9 Therefore we conclude that: The area of circle P is 9 times the area of circle Q
4] Is incomplete
5] Circumference is 32π, the diameter will be: C=πd where d is the diameter, thus: 32π=πd d=32 the answer is diameter is 32
