Answer:

r = $\sqrt{\frac{A}{\pi } }$

r = 17.2 cm

Step-by-step explanation:

∵ The area of the circle A = πr²

∴ r² = A/π

∴ r = √(A/π)

∵ A = 54 cm²

∵ π = 22/7

∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm

Answer:

w = 33.94 ft

Step-by-step explanation:the roof takes the shape of a right angle. The top of the roof is a right angle. To find the width of the house, which is the hypotenuse of the triangular roof, we would apply pythagorean theorem.

Thus:

$w^2 = 24^2 + 24^2$

$w^2 = 1,152$

Square both sides

$\sqrt{w^2} = \sqrt{1,152}$

$w = 33.94$ (to 2 decimal places)

The width of the house = 33.94 ft
