Answer:
- The surface area of the sphere in terms of r is 4πr^2 square units.
- The surface area of the cylinder in terms of r is 4πr^2 square units.
- The surface area of the cylinder and sphere are the same.
Step-by-step explanation:
The surface area of the sphere is given by the formula ...
A = 4πr^2
The surface area of the cylinder is given by the formula ...
A = 2πr^2 +2πrh
Here, the height (h) is equal to r, so this simplifies to ...
A = 2πr^2 +2πr·r = 4πr^2 . . . . . the same area as the sphere
Step-by-step explanation:
- step 2
Tanx= 8/10
tanx= 4/5
x= arctan(4/5)
x= 38.7 degrees
Step-by-step explanation:
For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.
Hence the answer is y = 5(x + 2).
