Answer:
40.56
Step-by-step explanation:
2pir
8÷2=r=4
2pi4=25.13
25.13÷2=12.565
10+10+8+12.56=40.565
Using the Pythagorean theorem:
a^2 + b^2 = c^2
A and B are the sides and c is the hypotenuse.
4^2 + 5^2 = c^2
Simplify:
16+25 = c^2
41 = c^2
Take the square root of both sides:
c=√41
The equation is 13.95x+1.95=85.65
The answer is 6 compact discs.
The answer is 72
You would have to add sixty-five plus seven
Well a percentage is basically a decimal. If we take the 20 and times it by 5,we can get a 100th of a decimal, 15/100= 0.15. Now we just change it to a percentage! 15%
