Answer:
7.1 feet^2
Step-by-step explanation:
The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:
area = π * r^2
area = 3.14 * (3/2 feet)^2
area = 7.065 feet^2 = 7.1 feet^2
Answer:
x = 1, y = -4
Step-by-step explanation:
7х + 2y = -1 ------ eq1
3х — 4y = 19 ------ eq2
multiply eq1 by 2
2 x (7х + 2y = -1)
14x + 4y = -2 -----eq3
by elimination, add equation 2 and 3
14x + 3x = 19-2
17x = 17 (divide both sides by 17)
x = 1 (answer)
substitute into eq1
7(1) + 2y = -1 (subtract 7 from both sides)
2y = -1 -7
2y = -8 (divide both sides by 2)
y = -8/2 = -4 (answer)
