Solution:
<u>Step-1: Find the area of the pizza.</u>
- Area of pizza = πr²
- => πr² = π x 9 x 9
- => 81π = Area of pizza
<u>Step-2: Find the area of the slice.</u>
- = 81π/6 = Area of slice
- => 27π/2 = 13.5π = Area of slice
Option D is correct.
Answer:
25 math problems
Step-by-step explanation:
He completed 10 out of x, or the total he has to do.
10/x
We know that this equals 40%
10/x=40/100
Cross multiply to solve
40*x=100*10
40x=1000
Divide both sides by 40
x=25
