What is the area of the circle in terms of pi? if the diameter is 10.2

Answer 1

To find the area of a circle in terms of pi, you can use the formula A = πr^2, where r is the radius of the circle.

Given that the diameter of the circle is 10.2, the radius (r) would be half of the diameter, so:

r = 10.2 / 2 = 5.1

Now, you can plug the radius into the formula to find the area:

A = π(5.1)^2
A = π(26.01)
A ≈ 81.17 square units

Therefore, the area of the circle in terms of pi is approximately 81.17 square units.
