The radius of a circle is 10 cm. Find its area in terms of piπ.
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle.
Given that the radius of the circle is 10 cm, we can substitute this value into the formula:
A = π(10)^2
A = π(100)
A = 100π
Therefore, the area of the circle is 100π square cm.
