Question

Factorize
πR² - πr² =
Thank you!

Answer 1

Answer:

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

Answer 2

Answer:

(πR+πr)(πR+πr)

Step-by-step explanation:

a²-b²= (a+b)(a-b)

So,

πR² - πr²

= (πR+πr)(πR+πr)

hope this helps u dear ❤️
