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>

(52)p = 512
52p = 512
p = 512/52
p = 9.85
p ≈ 10 (nearest whole number)
Answer:
The circumference of the wheel is 50.24 inches
Step-by-step explanation:
What I did was divide the diameter by two (Because you need to radi to get the diameter) to be sure of the answer. I then, multiplied the diameter by 3.14 to get 50.24in.
i think its a 50% chance or 1/2 chance of getting heads
