The question is not well stated. The answer can't be calculated without knowing the length of the cylinder.
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
The radius is 30 inches.
A=pi*r^2, so to find the radius, divide the area by pi and take the square root of that quotient. theta/360=arc length/circumference. C=2pi*r, so multiply the radius you found above by 2pi. Then you have theta/(known value)=(known value)/(known value), so you can now solve for theta!

Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
If cylinder radius and cylinder length are known : (pi = 3.141592654 . . . ) > Surface area = ( (2 * pi * radius) * length )
Radius is 30 inches.
The radius is 30 inches.
Curved surface area = pi*radius*slant length = 792 square cm radius = 792 divide by (pi*slant length)
The formula for the area of a rod, which is a cylinder, is given by A = 2πrh + 2πr^2, where A is the total surface area, r is the radius of the rod, and h is the length of the rod. The first term 2πrh represents the lateral surface area of the cylinder, which is the curved surface area, and the second term 2πr^2 represents the area of the two circular bases of the cylinder. By summing these two terms, we obtain the total surface area of the rod.
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
Knowing just the length of the base you can not work out the area. You need the height and the base or the length of the hypotenuse in order to work out the area.
