How do you find the surface area of a cylinder

Hey there!

The equation for the surface area of a cylinder would be circumference x height + 2B. The circumference is the perimeter of the circle. This is found by multiply the diameter by pi (3.14, though you should use the symbol π). The height is the height of the cylinder. The 2B is area of the 2 bases (the 2 circles on top and bottom of the cylinder).
An example of how to find the surface area of a cylinder is this: (given information) the radius of the circle is 5, and the height is 3. First, multiply the radius by 2 to find the diameter. This would be 10. Multiply 10 by pi. This would be 10π. Multiply the circumference of the circle by the height. 10π x 3=30π. Then, add the area of the 2 bases. The area of a circle is πr^2. Plug in 5 for the radius, or r. You get π5^2. This simplifies to 25π. Multiply by 2 because there’s 2 bases. You get 50π. Add. 30π+50π=80π. The answer to this problem is 80π units^2.

I hope this helps!

You multiply the circumference by the diameter then you solve for the circles on the top and bottom the add them up.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, t
Alenkinab [10]

Answer:

The triangle's perimeter is 61.77 inches.

Step-by-step explanation:

Since an altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles, and as a result, the altitude cuts the base into two equal segments, and the length of the altitude is 26 inches, and the length of the base is 9 inches, to find the triangle's perimeter the following calculation must be performed:

Isosceles triangle = 2 equal sides

To obtain the value of the sides, the Pythagorean theorem must be applied on the right triangle formed with the altitude.

(9/2) ^ 2 + 26 ^ 2 = X ^ 2

4.5 ^ 2 + 26 ^ 2 = X ^ 2

20.25 + 676 = X ^ 2

√ (20.25 + 676) = X

√696.25 = X

26.38 = X

26.3865 x 2 + 9 = X

52.77 + 9 = X

61.77 = X

Therefore, the triangle's perimeter is 61.77 inches.
