Can someone please help me? If you cannot think of anwer, leave me alone aight? I need somebody to explain why the surface area of the cylinder in the image is
351.86 square inches. Yes, i know the answer but still clueless how to solve for that. (There was a test and I got the answer wrong then it revealed the right answer)

Will mark brainliest if someone truly helps me.

Formula for to find out the surface area of a cylinder = 2πrh+2πr^2

As the radius of the cylinder (4/2) cm = 2cm

Then the surface area of the cylinder

= 2πrh + 2πr^2

=( 2×22/7×2×6 + 2×22/7 × 2^2) cm^2

= (528/7 + 176/7) cm^2

= 704/7 cm^2

=100.571428571 cm^2

=15.58860260571021 in^2 (ans)

This the answer

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
