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.
Answer:
-13n + 101
Step-by-step explanation:
88, 75, 62, 49. = -13 -13 -13 = -13n + 101 (as 88+13 = 101)
31 quarts, because there are 4 quarts in a gallon
Answer:
Point Y (4, -1) lies on the circle.
Step-by-step explanation:
Distance = √[(x2-x1)² + (y2 - y1)²] = √[(4-1)² + (-1-(-5))²] = √[3² + 4²]= √25 = 5
Point Y (4, -1) lies on the circle, because the distance from the center to this point equals radius of the circle.
