Step-by-step explanation:
lets radius be r and height be h,
r+h=21 -----(1)
curved surface area
2×pi×r×h=616 -----(2)
use simultaneous eqn to solve for r and h.
total surface area of cylinder= 2×pi×r×h + 2×pi×r²
= ans if im not wrong

Step-by-step explanation:
Answer:
A prime number is any number that cant be divide by any number but 1 (Ex. 1 2 3 5; Non-Ex. 4 6 8)
Answer:
Step-by-step explanation:
First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.
We know that 
, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.
Now that we have everything in cents, we can make the subtraction:
Replacing the value in cents we get:
A is quadratic function
B is equation of a circle
C is equation of a line
D is hiperbolic funciotn
