Since the circle touches each side of the square, it means that the length of the side (square) is equal to the diameter ( circle ). We are given the area of the square so we can solve the length of side.
s = diameter of circle
radius = diameter ÷ 2
radius = 12 ÷ 2
radius = 6 cm
Area of circle = pi x r x r
Area of circle = 3.14 x 6 x 6
Area of circle = 113.04 sq. cm.
#2
Area of rectangle = L x W
= 9 x 6
= 54 sq. m
Area of carpet = ( L - 1 ) x (W - 1 )
= 8 x 5
= 40 sq. m
Uncovered Area = Area of floor - Area of carpet
= 54 - 40
Uncovered Area = 14 sq. m
