Does the answer help you?
We can see that there are 5 CDs, each of radius 9 cm
<u>Area occupied by 1 disc:</u>
Area of a circle = πr²
Area of disc = π(9)²
Area of disc = 3.14 * 81 = 254 cm²
<u>Area occupied by 5 discs:</u>
Area occupied by 5 discs = Area occupied by 1 disc * 5
Area occupied by 5 discs = 254 * 5
Area occupied by 5 discs = 1270 cm²
I have no clue how to solve this myself but i would recommend using photomath for tricky equations because it gives you a step by step tutorial for the problem
It is not too difficult. Just do this
50-15
5(10-3)
The answer is 5(10-3)
