Answer: The cost of the trampoline cover would be $339.12
Step-by-step explanation: The radius of the trampoline is 4 feet (Diameter divided by 2 equals radius).
The trampoline cover will effectively cover the entire area of the trampoline and the area is given as
Area of circle = πr²
Area of circle = 3.14 x 4²
Area of circle = 3.14 x 16
Area of circle = 50.24 square foot
However the material costs $6.75 per square foot, which means the total cost of the trampoline cover would be derived as
Total area x cost per square foot = cost of trampoline cover
50.24 x 6.75 = Cost of trampoline cover
$339.12 = Cost of trampoline cover
Answer: The cost of the new trampoline cover is $339.29
Step-by-step explanation:
Hi, we have to calculate the area of the trampoline cover.
Since it has a circle form with a 8 ft diameter.
Area of a circle = π r^2
Since the radius (r) is equal to the diameter (d) divided by 2
R = d/2 = 8/2 =4
Replacing in the formula:
A = π 4^2 = 50.26 square ft
Since the material cost 6.75 per square foot
Cost = 6.75 x 50.26 = $339.29
