Given : एक वृत्ताकार शीट की परिधि 145 m हो  

To Find : त्रिज्या

शीट का क्षेत्रफल

Solution:

वृत्त की परिधि = 2πR

R =  त्रिज्या

π = 22/7

एक वृत्ताकार शीट की परिधि 145 m

=> 2 (22/7) R = 145

=> R = 145 x 7 / 44

=> R = 1015/44

=> R = 23.07

त्रिज्या   = 23.07 m

शीट का क्षेत्रफल  = π R²

= (22/7) (1015/44)²

= 1,672.44  m²
