A cylinder with a radius (r) and a height (h) has a surface area of:
π r2h2 |
|
π r2h |
|
4π r2 |
|
2(π r2) + 2π rh |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
What is 6a5 - 7a5?
| 13a10 | |
| -1a5 | |
| -a10 | |
| 42a5 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
6a5 - 7a5 = -1a5
If angle a = 32° and angle b = 47° what is the length of angle c?
| 69° | |
| 65° | |
| 101° | |
| 96° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 32° - 47° = 101°
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Odd |
|
Last |
|
Inside |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
(7a)(5ab) - (5a2)(3b)
(7 x 5)(a x a x b) - (5 x 3)(a2 x b)
(35)(a1+1 x b) - (15)(a2b)
35a2b - 15a2b
20a2b
