The area of the base of a cylinder is 100πm2. The volume of the cylinder is 900πm2. What is the height of the cylinder?

The area of the base of a cylinder is 100πm2. The volume of the cylinder is 900πm2. What is the height of the cylinder? Correct Answer 9m

আমরা জানি, সিলিন্ডারের ভূমির ক্ষেত্রফল = πr2এবং সিলিন্ডারের ভূমির আয়তন = πr2h প্রশ্নমতে, πr2 = 100π⇒ r2 = 100আবার, πr2h = 900π⇒ r2h = 900⇒ h = 900r2 = 900100 = 9.:. সিলিন্ডারের উচ্চতা =  9m
