Find the surface area of a cylinder with the height of 9 inches and base radius of 4

245.88 inches squared

Step-by-step explanation:

1. 2(3.14)^2 + 2(3.14)(4)(9)

2. 2(9.9) + 2(3.14)(4)(9)

3. 19.8 + 2(3.14)(4)(9)

4. 19.8 + (6.28)(36)

5. 19.8 + 226.08

245.88

Hope this helps you! :)

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)

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
