Question

You have a pan with a radius of 16 centimeters. if the cooking instructions say to cover the entire bottom of the pan with butter, how many square centimeters must the butter cover?

Answer 1

Radius of the pan = 16cm

Formula for area of circle:
           
                   $\boxed { \boxed { \text {Area of a circle =} \pi r^2}}$

Find the area of the pan:

                   $\text {Area of the pan =} \pi (16)^2 = 804.25 \ cm^2$

$\boxed { \boxed {\text {Answer : The butter must cover 804.25 cm}^2}}$
