Hey 20 points for the first person to show work and answer this

Harrizon [31]

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

$d = 18$

and, because the radium is half of the diameter,

$r = 9$

<u>Note that the units are inches.</u>

Using the equation

$a = \pi r ^{2}$

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

$a(s)= \frac{(\pi \times 9^{2})}{s}$

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.

A tabletop in the shape of a trapezoid has an area of 5,658 square centimeters. Its longer base measures 119 centimeters, and th

Sedaia [141]

The formula for finding the area of a trapezoid is: sum of bases*height*1/2
By plugging in the information that we already have, we know: (119+65)*height*1/2=5658
184*1/2*height=5658
92*height=5658
height=61.5cm.

Check:
119+65=184
184*61.5=11316
11316*1/2=5658

Solve for x:<br> Need help with this problem.

The sum of all angles in a triangle is equal to 180.

75 + 70 + 5 + 3x = 180

150 + 3x = 180

3x = 180 - 150

3x = 30

x = 10

Third angle:

5 + 3(10)
