Answer:

1st - 84. 2nd - Try doing this by yourself first and If you cant get it I'll help you.

Step-by-step explanation:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Which expression represents the approximate length
Viktor [21]

The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)

<h3>Trigonometric Ratios</h3>

From the given triangle ABC, we see that;

∠A = 66°

∠C = 38°

AB = 3

Thus using sine rule, we have;

AB/sin C = BC/sin A

3/sin 38 = BC/sin 66

BC = (3sin 66)/sin 38

BC = 4.45

A homeowner wants to build a circular patio. if the diameter of the patio is 20 feet, what is its area to the nearest whole numb
andreyandreev [35.5K]
We are asked to find the area of patio. It is circular so formula used for area is given by:
A= r^{2}  \pi
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet

A = 10^{2} \pi =100 \pi
When we round this to the nearest whole number:
A =100 \pi = 314.159=314ft^{2}
