To find the inverse, interchange the variables and solve for y
hope this helps!
1. The answer would be about 20.72, or 20.7142 if you don’t want the rounded version
2. The answer is -12.8
7.6 x 1/10^5
=7.6 x 1/100,000
=0.000076
To solve this you multiply -4.5 by 2.5
Your answer is -11 and 1 /4
To calculate the are of the sides of a cylinder, you take the circumference of the base, or circle, and multiply it times the height. To calculate the circumference of a circle we use the formula 2*pi*r, or 15pi. We multiply this times 20 to get 300pi cm. If you are using 3.14 for pi, this is 942, or if you are using actual pi, around 942.4777.
