PLEASE HELP what is the volume of the cone to the nearest cubic foot? (use 3.14)

115 ft3

297 ft3

462 ft3

594 ft3

461.81

Step-by-step explanation:

V = 3.14 times radius ^2 h/3

V = (3.14) ×7^2 9/3

V = 461.81

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
