find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and radius of the base is 7 cm

--- Curved Surface Area

 --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

-- height

--- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

This gives:

Solving (b): The total surface area (TSA)

This is calculated as:

This gives:

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
