Answer:
1861.39 cm²
Step-by-step explanation:
Given:
d = 15 cm
radius (r) = ½(15) = 7.5 cm
Height = 32 cm
Surface area of a cylinder = 2πrh + 2πr²
Plug in the values
Surface area = 2*π*7.5*32 + 2*π*7.5²
= 1861.39 cm²
Answer:

Step-by-step explanation:
We need to sum the following two expressions:


expanding the polynomial in the numerator:


This is the most simplified form we can get:

Answer:
-4
Step-by-step explanation:
P^5 / P^2
The base are equal, so we should to subtracting the powers only
Dividing exponential expressions
P^5 / P^2 = P^(5-2)
:. = P^3
