Answer:
Surface area of a cone = πrs + πr2
Volume of a cone = 1/3πr2h.
The slant of a right circle cone can be figured out using the Pythagorean Theorem if you have the height and the radius.
Answers for volume problems should always be in cubic units.

Answer:
- f(-2) = -14
- g(7) = -29
Step-by-step explanation:
~1
Given Polynomial:
- f(x)=2x²-3x
To Find:
- f(-2)
Solution:
- f(x)=2x²-3x
Substitute x = -2 onto the given polynomial,as we need to find f(-2),so x = -2.
- f(6) = 2(-2)² -3(-2)
Simplify using PEMDAS,then.
- f(6) = -8 - 6
- f(6) = -14
Hence, f(6) = -14
~2
Given polynomial:
- g(x) = -4x-1
To Find:
- g(7)
Solution:
g(x) = -4x-1
Substitute x = 7 onto the given polynomial,as we need to find g(7),so x = 7.
- g(7)= -4(7) - 1
Simplify using PEMDAS.
- g(7) = -28 - 1
- g(7) = -29
Hence, g(7) = -29.
