দুটি বৃত্তের পরিধি যথাক্রমে 198 সেমি এবং 352 সেমি।
ব্যবহৃত ধারণা:
দুটি বৃত্তের পরিধি = 2πr
যেখানে, r = ব্যাসার্ধ
গণনা:
ধরা যাক দুটি বৃত্তের ব্যাসার্ধ হল r 1 এবং r 2
প্রশ্ন অনুযায়ী,
2πr 2 - 2πr 1 = 352 - 198
⇒ 2π(r 2 - r 1 ) = 154
⇒ π(r 2 - r 1 ) = 77
⇒ আর 2 - r 1 = 77 × 7/22
⇒ আর 2 - r1 = 49/2
⇒ আর 2 - r 1 = 24.5
∴ প্রয়োজনীয় উত্তর হল 24.5 সেমি
