Answer:

-20a - 65 = -104 for a = 2.7

-6x + 52 = 45 for x = 1 1/6

Step-by-step explanation:

-20a - 50 for a = 2.7

Insert 2.7 in for a.

-20(2.7) - 50 = -54 - 50 = -104

-6x + 52 for x = 1 1/6

Insert 1 1/6 for x.

-6(1 1/6) + 52 = -7 + 52 = 45

What’s the correct volume ?

nikitadnepr [17]

Answer:

V = 12π

Step-by-step explanation:

Given radius of cone, r = 3 and y = 5

by Pythagorean theorem (or by recognizing that this is a standard 3-4-5 right triangle), we can determine that height of cone, x = 4 in

volume of cone is given by :

V= (1/3) πr²x

= (1/3) x π x 3² x 4

V = 12π
