Answer:

200π; 628

Step-by-step explanation:

The volume of a cone can be found with the formula:

V=πr^2(h/3)

Now, we can plug the values that we know in.

Height is 6

Radius is 10

That said, our equation is now:

V=π10^2(6/3)

Simplify.

V=π100(2)

V=200π

Or, using 3.14 for pi it would be:

200(3.14)

628

1. f(x) = 2x + 6 Evaluate f(2)

fredd [130]

1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10

2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3

f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18

f(2)+f(3)=5+18
=23.
