Question

The area of the base of cylindrical tube is pie cm2. What is the radius of the base?

Answer 1

the base of cylindrical tube is a circle

given

area of circle = π cm2

πr^2 = π

r ^ 2 = 1

r = 1 cm ( ignoring negative value)

Answer 2

Concept

One of the most fundamental curvilinear geometric forms, a cylinder has historically been a three-dimensional solid.

Given

A area of base of cylindrical tube is given which is π cm²

Find

We have to find the radius of base of cylindrical tube

Solution

The steps are as follow:

• The formula for area of base is π*r² which is given π

area of base = π = π*r²

∴ π = π*r²

∴ r² = 1

∴ r = 1

Hence the radius of base of cylindrical tube will be 1 cm
