Question

A circular patio has a radius of 4 yards. The patio is expanded so that the radius increases by 2 yards.

Answer 1

Answer:

50.29 yards^2

113.14 yards^2

62.85 yards^2

Step-by-step explanation:

Area of a circle = πr²

π = pi = 22/7

r = radius

original area

(22/7) x 4² = 50.29 yards²

New area

radius = 4 + 2 = 6

(22/7) x 6² = 113.14 yards²

Increase in the area of the patio = 113.14 yards² - 50.29 yards²=62.85
