Answer:
25.12cm
Step-by-step explanation:
So we first find the area of the circle on top:
area= 
or 3.14 x 
which equals 12.56
Then we multiply it by 2:
12.57 x 2 = 25.12
So the lateral surface area is 25.12cm
Answer:
40%
Step-by-step explanation:
A percent is;

It is given that Jolie the 75 dodgeballs in total, hence the whole is 75. It is also given that 30 of the dodgeballs hit the target, so the part is 30. Now all one has to do is solve for "x".

Simplify
by dividing the numerator and denominator by 15.

Now the equation is;

Typically, one would solve a proportion by doing cross products, but in this case, it is easier to think about it intuitively. Since 5 is a factor of 100 (5 * 20 = 100), then all one has to do is multiply
by 20 to get the answer (on the numerator).
x = 40
