Answer:
B. 5x+4
Step-by-step explanation:
Solving this is quite easy.
- Add 5x and 4 getting 5x+4
- Look at your bottom variables..since 7x and -7x are opposites they will cancel out! And same thing goes for y and -y.
Answer: CSA = 22.9m^2
Step-by-step explanation:
The cross sectional area of the cylinder perpendicular to the length, is the area of the circular base or top of the cylinder. It can be derived mathematically using the area of a circle.
Cross sectional area = πr^2
Where r is the radius of the cylinder
r = 2.70m
CSA = π×2.70^2
CSA = 22.9m^2
