1. The area of a circle is
a = \pi {r}^{2}
\pi = 3.14 \\ r =  \frac{3.4}{2}  = 1.7
a = (3.14) {(1.7)}^{2}  \\  = 9.0746
The area is 9.07 cm^2.

2. The volume of a cube is
v =  {s}^{3}
s = 4.5
v =  {(4.5)}^{3}  \\  = 91.125
The volume is 91.125 m^3

The length of a rectangle is 5 inches more than the width. The area is 33 square inches. Find the length and width . Round to th
EleoNora [17]

Answer:

the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.

Step-by-step explanation:

The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as

A = L * W

As such, given that the length is 5 inches more than the width,

L = W + 5

33 = W(W + 5)

W² + 5W  - 33 = 0

Using the formula method which states that

s = -b±√(b²-4ac)/2a

W = -5 ± √5² - 4(1)(-33)/2

= -5 ± 12.53/2

= 7.53/2 (since length cannot be negative)

= 3.755 inches

L = 3.755 + 5

= 8.755 inches
