Question

Emma is making a scale drawing of her farm using the scale 1cm = 2.5ft. In the drawing she drew a well with a diameter of 0.5 centimeter. Which is closest to the actual circumference of the well?

Answer 1

Scale : 1 cm = 2.5 ft

1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft

Circumference = πD = π(1.25) = 3.93 ft

Answer: 3.93 ft
