Answer 2

Answer:

r= X+5

Step-by-step explanation:

Area = πr²

Find r:

Given that area =  πx²+10πx+25π

πr² = πx²+10πx+25π

Take out common factor π:

πr² = π(x²+10x+25)

Divide by π on both sides:

r² = x²+10x+25

Factorise the right hand side:

r² = (x + 5)²

Square root both sides:

r = x + 5
