What is the difference in the areas of a circle with diameter 4 m and a circle with diameter 6 m?
lidiya [134]
Hello!

To solve this you need to use the equation to find the area of a circle which is

A =  \pi  r^{2}

A is area
r is radius

Solve both circles
------------------------------------------------------------------------------------------------------
Circle 1
A =  \pi  4^{2}

Square the number

A = 16 \pi
------------------------------------------------------------------------------------------------------
Circle 2

A = \pi  6^{2}

Square the number

A = 36 \pi
------------------------------------------------------------------------------------------------------
Finding the answer

To get the answer you subtract the numbers

36 \pi  - 16 \pi  = 20 \pi

The difference is 20  \pi which is about 62.83 units

Hope this helps!
