The equation for the surface area of a cylinder is 2πr^2+2πrh.
we substitute our values of the radius and the height to find our answer.
so 2xπx5^2+2xπx5x10 = 471.238898m^2
Okay. All we have to do is divide the price by 6, because 6 people are putting in money to help pay off the total price. So 61.56/6= 10.26. Each person would would pay $10.26 to help cover the total dinner cost.
The square of the distance between C(4, -5) and P(1, -2) is given by the Pythagorean theorem as
(4-1)² +(-5-(-2))² = 18
This is the square of the radius of the circle, so we can use it for r² in the formula
(x -h)² +(y -k)² = r² . . . . . . . circle of radius r and center (h, k)
Your circle has equation ...
(x -4)² +(y +5)² = 18
You can use 6-2=4
You just Subtract the 2 from 6 and that gives 4
The answer is C The distance between the points (15,6) and (21,22)
