Find the surface area of the cylinder. Use 3.14 for π.

See explanation

Step-by-step explanation:

The surface area of a cylinder is calculated using:

Given that the radius of the cylinder is r =7 units and the height of the cylinder is 3 units, and π=3.14

Then we substitute to obtain.

We simplify to get:

We multiply out to obtain:

We finally get:

Therefore the surface area is 62.8 square units

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
