Let g(x)=-x^2+8x+4. find g(-5)

-11

Step-by-step explanation:

g(-5)=-5^2+8(-5) +4

=25+-40+4

=-11

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
