Step-by-step explanation:
812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...
812.30/83 ~ 9.8
Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.
The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>

(3.5) (14) + 2</span><span>

(3.5)^2
If we simplify this expression, we get:
98</span><span>

+ 24.5</span><span>

If you simplify once more, you get
122.5</span><span>

or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>

or about 384.85<span>

C=2(3.14159...)R
You’re given the circumference, so all you need to do is plug that in and simplify.
36=2(3.14159...)R
36=6.28R
36/6.28=R
R is about 5.73
