If a = c = 8, b = d = 1, what is the area of this rectangle?

79% Answer Correctly
2
8
5
45
Solution

The area of a rectangle is equal to its length x width:

a = l x w
a = a x b
a = 8 x 1
a = 8

2

What is 5a3 + 4a3?

75% Answer Correctly
9
a36
a6
9a3
Solution

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.

5a3 + 4a3 = 9a3

The dimensions of this cube are height (h) = 2, length (l) = 1, and width (w) = 1. What is the surface area?

51% Answer Correctly
78
10
210
104
Solution

The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):

sa = 2lw + 2wh + 2lh
sa = (2 x 1 x 1) + (2 x 1 x 2) + (2 x 1 x 2)
sa = (2) + (4) + (4)
sa = 10

4

The dimensions of this cylinder are height (h) = 3 and radius (r) = 6. What is the surface area?

48% Answer Correctly
40π
108π
20π
8π
Solution

The surface area of a cylinder is 2πr2 + 2πrh:

sa = 2πr2 + 2πrh
sa = 2π(62) + 2π(6 x 3)
sa = 2π(36) + 2π(18)
sa = (2 x 36)π + (2 x 18)π
sa = 72π + 36π
sa = 108π
