Which equation can be used to find the surface area of the cylinder?

the first option

Step-by-step explanation:

the formula to find the surface area of a cylinder is

2πrh+2πr²

A=2πrh+2πr2=2·π·4·16+2·π·42≈502.65482

Step-by-step explanation:

its b

step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
