Best answer
मान लीजिये वृत्त की त्रिज्या r सेमी. है |
`:." ""व्यास "=2r" सेमी. तथा परिधि "=2pi r" सेमी."`
यह दिया है की वृत्त की परिधि उसके व्यास से 16.8 सेमी. अधिक है |
अर्थात `" ""परिधि"= "व्यास"+16.8`
`implies" "2pi r=2r+16.8`
`implies" "2((22)/(7))r=2r+16.8`
`implies" "44r=14r+16.8xx7`
`implies" "44r-14r=117.6`
`implies" "30r=117.6`
`implies" "r=(117.6)/(30)=3.92.`
अत: त्रिज्या = 3.92 सेमी.
