Asked by Mathew Jameson

Tomaz draws a circle and dilates it on a photocopier using a scale factor of 3. If the original circle has a radius of 3 cm, what is the area of the dilated circle? Round your answer to the nearest tenth of a square centimeter.

The dilation multiplies the radius by 3, so the new radius is 9 cm. Area = πr^2 = π(9^2) = 81π ≈ 254.5 cm² (to the nearest tenth).
