Step-by-step explanation:
perimeter formula is adding up all the sides
so
5x-40 + 5x-40 + 3x-18 + 3x -18
= 16x -116
Answer:
63
Step-by-step explanation:
first yoy need to put the biggest number on the top then multiply each number
Step-by-step explanation:STEP 1: Draw two straight, intersecting tangent lines onto the circle. The lines can be completely random. However, the process will be easier if you make them roughly square or rectangular.
STEP 2: Translate both of the lines to the other side of the circle. You will end up with four tangent lines forming a parallelogram or a rough rectangle.
STEP 3: Draw the diagonals of the parallelogram. The point where these diagonal lines intersect is the circle's center.
STEP 4: Check the accuracy of the center with a compass. The center should be on target as long as you didn't slip while translating the lines or when drawing the diagonals. Feel free to erase the parallelogram and diagonal lines.
The volume of the cylinder is 602.88 ft³.
The surface area of the cylinder is 301.44 ft²
<h3>How to find the volume and surface area of a cylinder?</h3>
volume of a cylinder = πr²h
volume of a cylinder = 3.14 × 4² × 12
volume of a cylinder = 3.14 × 16 × 12
volume of a cylinder = 602.88 ft³
Surface are of a cylinder = 2πr(r + h)
Surface are of a cylinder = 2 × 3.14 × 4(4 + 8)
Surface are of a cylinder = 25.12(12)
Surface are of a cylinder = 301.44 ft²
