"Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. Use 3.14 for pi."
1 answer:
The volume of a cone is calculated by multiplying the area of the base and the height divided by 3. It is expressed as follows:
V = πr²(h/3)
We calculate as follows:
83.74 = πr²(5/3)
r = 4.00 in
D = 2r = 2 x 4.00 = 8.00 inches

Answer:
x = -3
Step-by-step explanation:
x + 3y = -5
x = -3y - 5
2(-3y - 5) - y = 11
-6y - 10 - y = 11
-7y - 10 = 11
-7y = 21
y = -3
50 = 25 * 2 = 5 * 5 * 2
44 = 22 * 2 = 11 * 2 * 2
Is the surface a rectangle?? If so, then the surface area would be 35
