alleryr = 7 cm மற்றும் l = 25 cm கொண்ட ஒரு கூம்பின் மொத்தப் புறப்பரப்பைக் காண்க (pi = 22/7).
A704 cm²
B858 cm²
C154 cm²
D550 cm²
Answer & Solution
Correct answer: A. 704 cm²
மொத்தப் பரப்பு pi r (l + r) = 22 x 32 = 704 சதுர சென்டிமீட்டர் ஆகும், இது வளைபரப்பு 550 உடன் அடிப்பரப்பு 154 கூட்டப்பட்டதாகும்.
