Answer:
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.
Step-by-step explanation:
The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.
If the radius of the base is

and the height is

, then the surface area of the cylinder is

You're given that the area is

and the radius is

, so you have
Answer:
y=5
Step-by-step explanation:
all you have to do is divide 6 on both sides
to get 5 cause negatives cancel
