Question

39) Total surface area of a cylinder is 500cm’ and its lateral surface area is 300 cm², then the area of its each circular base is. A) 100cm B) 75cm C) 50cm D) 200cm​

Answer 1

Answer:

its A) 100 cm

Step-by-step explanation:

Total Surface Area Given = 500 cm

Lateral Suraface area Given = 300 cm

Total Surface Area = Lateral Surface area + 2( Area Of Circular Base )

So, 500 = 300 + 2( Area of Circular Base )

     500 - 300 = 2 ( Area of Circular Base )

     200 =  2 ( Area of Circular Base )

     200/2 = Area of Circular Base

     100 cm = Area of Circular Base
