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