The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂
Since the area of a circle is

,
SA = 2*(

) + A₂
Since the area of the side is height * the circumference of the circle or A₂ = h *

, then SA must be;
SA =

SA =

SA =

SA ≈ <span>351.858377202</span>
Answer:
? = 14
Step-by-step explanation:
let us say that ? = x
7^x * 7^5^4 = 7^34
When you have a power to a power you multiply
7^x * 7^20 = 7^34
when you multiply common bases you add the power. since all the bases aer the same just look at the power
7^34-20 = 7^x
7^14 = 7^x
Depends on how many you have
When you multiply exponents with the same base, you add the exponents.
3+-5+y=-2
-2+y=-2
y=0
Final answer: y=0
Quotient is the result of a division.
1 - 1/x
