ANSWER :- (b) r²

 \bf\huge\underline{\underline{ Given :- }}

  • x = r sin Q

  • y = r cos Q

 \bf\huge\underline{\underline{ To \: Find:- }}

  • x² =( r sin Q)²

  • = r² sin² Q

 \rule{10cm}{0.05cm}

  • y² = (r cos Q)²

  • = r²cos²Q

 \rule{10cm}{0.05cm}

  • x² + y² = r²sin²Q + r²cos²Q

  • = r²(sin²Q + cos²Q)

  • = r²
