circumference= 2pie r. 2pie r=6r+2 solving this we get r=7. Are =pie r square + 22/7*7*7= 154 sq. units

C = 6r+2 = 2(pi)r 6r+2 =6.28r 0.28r=2 r=7.143(approx) ...(i) put the value of "r" in (ii), area of circle = pi(r*r) ...(ii)

Given: circumference of circle = 2 + 6 (r) find: area Solution: 2 * pi * r = 2 + 6r 44/7r = 2 + 6r 44/7r - 6r =2 2/7r = 2 r=7units area pi * 49 = 154 Sq. Units

Follow these steps to find the area of a circle. You will also learn how to find the area of a sector 1Calculate the length of the radius. If you only know (or have measured) the diameter (the distance from one side of the circle to the other), then divide it by two to obtain the radius. The radius... read more

Circumference of a circle= 2piR according to ques 2piR is 2 more then 6R so 2piR=6R+2 from this eq. we can find R and then area of circle is pi*(R^2) putting the value of R we can find the answer.

2*?*r=6r+2 ?*r=3r+1 (?r-3r)=1 r(?-3)=1 r=1/(?-3) Now area =?*r*r A=?*((1/(?-3)*1/(?-3)) A=?/((?*?)-6?+9)
