Question

A. What is the circumference of the

largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for Pie


b. What percent of the perimeter of the
square is the circumference of the
circle?

Answer 1

a) 94.2 cm

b) 78.5%

Explanation:

a) since the square side = 30 cm

it means the diameter = 30 cm

then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm

b) the perimeter of the square = 30×4 = 120

94.2 for 120

x% for 100%

x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%
