Question
The city is putting a fountain at the entrance of the park. A scale drawing of the fountain is shown below.
A circle with a radius of 2
Scale
1 in. : 4 ft
What is the area of the fountain in square feet?
Responses
A 4π4 π
B 16π16 π
C 64π64 π
D 128π
B 16π16 π
Area of a circle = Οr^2
Area = Ο(2)^2
Area = 4Ο
Using the scale factor of 1 in. : 4 ft, the area in square feet would be 4^2 * 4Ο = 16Ο, which corresponds to option B.
