So the question ask to find how to integrate cos2t without using substitution and base on my research, the integral of the cos2t = (1/2) sin(2t), and negate the said integral because the derivative of cosx is - sinx. I hope you are satisfied with my answer and feel free to ask for more
The area of the geometry is the sum of the area of the triangle and the semicircle will be 49.12 square feet.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The geometry is the combination of the semicircle and right triangle.
Then the area of the geometry will be
Area = 1/2 x 6 x 8 + π/8 x 8²
Area = 4 x 6 + 3.14 x 8
Area = 24 + 25.12
Area = 49.12 square feet

Answer:
2 pi*r^2 + 2 * pi *r * h
Step-by-step explanation:
I will assume that you are looking for surface area
We need to find the area of the top and the bottom, which is the area of a circle
top: pi * r^2
Bottom: pi r^2
Then the side which is the circumference times the height ( it is a rectangle)
side: 2 * pi *r * h
Add them together to get the surface area
SA = pi * r^2 + pi * r^2 + 2 * pi *r * h
= 2 pi*r^2 + 2 * pi *r * h
