Answer:
17.106 Teaspoons of fertilizer
Step-by-step explanation:
Joni has a circular garden with a diameter of 16.5. If she uses 2 teaspoons of fertilizer for every 25 square feet of garden how many teaspoons of fertilizer will Joni need for her entire garden?
Step 1
We calculate the area of the garden.
The garden is circular in shape.
Area of a circle = πr²
r = radius = Diameter/2
Diameter = 16.5 ft
r = 16.5/2
r = 8.25 ft
Area of the circle = π × 8.25²
Area of the circle (Garden) = 213.82464998 ft²
Approximately = 212.825ft²
Step 2
If she uses 2 teaspoons of fertilizer for every 25 square feet of garden how many teaspoons of fertilizer will Joni need for her entire garden?
25 ft² = 2 teaspoons of fertilizer
212.825ft² = x
Cross Multiply
25 ft² × x = 212.825ft² × 2
x = 213.825× 2/25 ft²
x = 17.106 Teaspoons of fertilizer
