What is the ratio of the area of Circle M to the area of Circle K?

Correct Option: 2
Diamter of Circle M =15=15 feet, so Radius =152=7.5=\frac{15}{2}=7.5 feet
Area =π(7.5)2=56.25π=\pi(7.5)^2=56.25\pi square feet
Diameter of Circle K =15+15=30=15+15=30 feet, so Radius =302=15=\frac{30}{2}=15 feet
Area =π(15)2=225=\pi(15)^2=225 square feet
Ratio of Area of Circle M to Area of Circle K =56.25225=1:4=\frac{56.25}{225}=1:4
