The radius of a circle is 98mm. What is the area of the circle.
The formula for the area of a circle is A = πr^2, where r is the radius.
Substituting the given value of the radius,
A = π(98mm)^2
A = π(9604mm^2)
A ≈ 30,589mm^2
Therefore, the area of the circle is approximately 30,589 square millimeters.
