Given : A triangular flowerbed is being planted inside a circular area of grass.
To Find : What is the area of the grass (the area surrounding the flowerbed)? (Use 3.14 for π.)
3,315.74 ft²
9,212.96 ft²
8,996.96 ft²
1,965.74 ft²
Solution:
Diameter = 58 ft
Radius = 58/2 = 29 ft
Area of circle = πr²
= π(29)²
= (3.14) 29²
= 2,640.74 ft²
Area of right angle triangle = (1/2) * 27 * 50 = 675 ft²
area surrounding the flowerbed = 2,640.74 - 675
= 1965.74 ft²
