Question

A large soda bottle cap has a radius of 1+2√2 centimeters. What is the area of the bottle cap? (Recall that the area of a circle is πr^2 where r is the radius).

Answer 1

The solution to the problem is as follows:

Given:

radius = 1+2√2 

Required: 

Area

Solution:

Area = pi*r^2 = (3.14)(1+2√2 cm)^2  = 46.05 cm^2

Therefore, the area of the bottle cap with radius 1+2√2  cm is 46.05 square centimeters.

I hope my answer has come to your help. God bless and have a nice day ahead!
