Answer:

No solution

Step-by-step explanation:

x=-3y-5.....(1)

3x+9y=7.....(2)

from equation (2)

3(-3y-5)+9y=7

combine

-9y-15+9y=7

collect the like terms

-9y+9y=7-15

0=-8

Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to
scoundrel [369]

Answer:

V = \pi r^2 h

And for this case the value for the height is h = 10.7 in the diameter is provided D = 2r = 8.1 in so then the radius is given by:

r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in

Then we can find the volume with the first formula and replacing we got:

V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3

The final answer for this case would be 551.4 cubic inches

Step-by-step explanation:

The volume for a right circular cone is given by this formula:
