Answer:
Circumference = 31.42m
Area = 78.54m
Explanation:
First of all we need to find the radius as its necessary for both answers.
radius = diameter/2. In this question the diameter is 10m meaning the radius is 5m.
-Circumference = 2πr
-c = 2π(5m) = 31.42m (rounded)
-Area = πr^2
-a = π(5m)^2 = 78.54m (rounded)
