Multiply by 4 to get rid of fraction
4(18) = 4(x/4 + 7)
72 = x + 28
x = 44
Solution; x = 44
9,6^2+18,8^2=X^2
92,16+353,44=X^2
X^2=445,6
X=21
Answer:
The area of the roof: ≈2287.44 ft^2, the lateral area of the roof:≈1580.58 ft^2
Step-by-step explanation:
The area of the roof is computed by the equation of the area of a cone:
A = πr(r +
)
(r: radius, h: height, πr^2 is the area of the base of the cone, πr
is the lateral area of the cone). So:
A =
≈ 2287.44 ft^2.
As I stated earlier, the lateral area of the roof can be computed:
A
=
≈ 1580.58 ft^2.
