The area of the ground in the park that is covered with grass is 821.5 square yards ⇒ 1st answer
Step-by-step explanation:
Let us revise the areas of some figures
- Area of a square of side length s is A = s²
- Area of a circle of radius r is A = πr²
∵ The park is shaped a square
∵ The side length of the park is 30 yards
- Use the rule of the area above to find the area of the park
∴ Area of the park = (30)² = 900 yards²
∵ The pool is shaped a circle
∵ The diameter of the pool is 10 yards
- The radius of a circle is half its diameter
∵ r = [tex]\frac{1}{2}[/tex] diameter
∴ r = [tex]\frac{1}{2}[/tex] (10) = 5 yards
- Use the rule of the area above to find the area of the pool
∵ π = 3.14
∴ Area of the pool = 3.14(5)² = 78.5 yards²
To find the area of the ground in the park that is covered by grass subtract the area of the pool from the area of the park
∴ Area of the ground = 900 - 78.5
∴ Area of the ground = 821.5 yards²
The area of the ground in the park that is covered with grass is 821.5 square yards
