Answer:
12.83 inch^2
Step-by-step explanation:
To calculate the area of each piece, we need to first need to calculate the area of the pizza as a whole.
Mathematically the area A of the pizza can be calculated using the formula;
A = π * r^2
where our r here is 7 in
Thus, A = 22/7 * 7 * 7 = 154 inch^2
The area of each piece of the pizza is thus 154/12 = 12.8333333 inch^2
To the nearest hundredth, this is 12.83 inch^2

Answer:
The correct answer is C) 7,200.
Step-by-step explanation:
In order to find the answer for this, start by using the formula for momentum.
Mo = M*V
Mo = 120 * 60
Mo = 7,200
Answer:
22/35
Step-by-step explanation:
3/7 + 1/5
First, find a common denominator.
7*5=35 multiply the numerator by 5 too: 3*5=15
5*7=35 multiply the numerator by 7 too: 1*7=7
15/35 + 7/35
=22/35
Cannot be simplified.
Answer:
17
Step-by-step explanation:
let x be the number of boxes to be shaded to make it 80%
x = 80% of total number
= 80/100 of 25
= 80/4
= 20
So 20 need to be shaded to fill 80%
Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13
= 17 squares
