Answer:
31.8 in^2 per slice
Step-by-step explanation:
to get the radius (r) you divide the diameter (d) by 2, so its 18/2 which is 9, then you plug 9 into the formula for a circle
A=πr2=π·92≈254.469
thats the area for the whole pizza, then you divide that by 8 (for the 8 slices) which is 254.47/8, which gives you 31.80875
31.80875 rounds to 31.8 in's, but you have to make sure its in^2 because its area
Answer:
116 = 116.
Step-by-step explanation:
Because the equations are the same, x + 4, they will always be equal to each other. 4 + 112 = 116.

Answer:
She should use the formula to find a diameter of 16 inches.
Step-by-step explanation:
The circunference of a circle is given by:
In which r is the radius, which is half the diameter. So, it can also be given by the following formula:
In which d is the diameter.
Which formula should Maria use to help her find the diameter of the rug?
She should use this formula:
Since the circunference is 50.24 inches, the diameter will be of:
2x-y=11 ,6x-3y=15
4x+4y=26
-4y. -4y
4x=22
4. 4. divided
x=5.5 if its wrong and fix something that's wrong
