Question

2π(a-r)(a+r)+4 = 52π
Can someone solve this pleaseeeee

Answer 1

a²-r²= 22

Explanation:

2π(a-r)(a+r)+4 = 52π

=> 2π(a²-r²)+4= 52π

=> (a²-r²)+4 = 52π/2π

=> (a²-r²)+4 = 26

=> (a²-r²)= 26-4

=> a²-r²= 22

Answer 2

=> a²-r²= 22

Explanation:

2π(a-r)(a+r)+4 = 52

=> 2π(a²-r²)+4= 52π

=> (a²-r²)+4 = 52π/2π

=> (a²-r²)+4 = 26

=> (a²-r²)= 26-4

=> a²-r²= 22
