Answer is 30
Multiply top of bottom of each fraction to get 30 on the bottom
So 2m/5•6 and 2m/6•5
First, you have to calculate the height.
Pythagorean Theorem:
a^2+b^2=c^2
Slant height=c^2
Radius=b^2
So, a^2+6^2=16^2
a^2+36=256
a^2=220
a=14.832397
Surface Area = πr(r+ square root of h^2+r^2)
Surface Area is approximately 414.69
The answer is 13.23 becase in the parenthesis is negative and neg times a neg makes a positive value :)
