If the daimeter of a solid cylinder with lenght 140cm is 8cm , find its curved surface area ,

Given:

Diameter of a solid cylinder = 8cm

Length (height) of cylinder = 140 cm

To find:

The curved surface area of the cylinder.

Solution:

We have,

Diameter = 8cm

Radius =

Height = 140 cm

Curved surface area of a cylinder is

where, r is radius and h is height.

Putting r=4 and h=140 in the above formula, we get

Therefore, the curved surface area of the cylinder is 3520 square cm.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
