In designing a new garden, Al has budgeted $215 a circular patio next to the garden. The diameter of the patio is 15 feet and concrete is $0.32/ft2 . Explain if Al has enough budgeted for the patio?
Circumference of patio = dπ
= 15π feet
= 15 * 3.142 feet (taking π = 3.142)
= 47.13 feet
What do you mean by "concrete"? If we are asked if Al has enough budgeted for the patio, then we must find the height of the patio!!
I will now assume that the height of the patio is h feet.
47.13 * h = 47.13 h square feet
47.13 h square feet * $0.32 ≈ $15.08 h
If :
$15.08 h > $215, then Al doesn't have enough money budgeted.
If:
$15.08 h ≤ $215, then he has enough money budgeted.
