Answer: A≈1385.44m²
Explanation:
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·422≈1385.44236m²
If the diameter of a circular pond is 42 m. Then the area of the pond will be 5541.77 square meters.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
