Question

the different between the circumference and radius of a circle is 37 centimetre find the area of the circle​

Answer 1

Answer:

AREA OF THE CIRCLE = 154 CENTIMETRE SQUARE

Step-by-step explanation:

⇒ CIRCUMFERENCE OF CIRCLE = 2$\pi$R = 37 cm

⇒  NOW BY THE QUESTION ,

    = 2$\pi$R - R = 37

    = R( 2$\pi$ -1 ) =37

    = R ( 2×22÷7-1 ) = 37

    = R ( 44÷7-1 ) = 37

    = R ( 37÷7 )  = 37

      ∵  R = 37×7÷37

       ∴  R = 7 cm

⇒ AREA OF CIRCLE = $\pi$×R SQUARE

                                  = $\pi$× 7×7

                                  = 22÷7×49

                                  = 22×7

                                  = 154 SQ. cm
