Question

Area of two circles whose radius are R1 and R2 MCQ​

Answer 1

Area of First Circle = Pie x R1^2 x h
Area of Second Circle = pie x R2^2 x h

Answer 2

Answer:

area of a circle = πr²

here radius r = R1 and R2

area of circle 1 =  πR1²

area of circle 2 =  πR2²

sum of area of 2 circles =  πR1²+ πR2²

                                        =    π(R1²+R2²)
