Question

find the total surface area of a right circular cylinder whose height is 7 cm and the radius of its base is 10 cm

Answer 1

➡ Formulae of Cylinder : ➡


✏ Volume of Cylinder = πr²h

✏ Curved Surface Area of Cylinder = 2πrh

✏ Total Surface Area of Right Circular Cylinder = 2πrh (r+h)


✒ Given :

→ Height of Cylinder = 7 Centimeters

→ Radius of Cylinder = 10 Centimeters


✒ To Find : Total Surface Area of Right Circular Cylinder ?


✒ Solution :



→ Total Surface Area of Right Circular Cylinder = 2πr(r+h)


→ Total Surface Area of Right Circular Cylinder = 2×22/7 × 10 (10+7)


→ Total Surface Area of Right Circular Cylinder = 44/7× 10(17)

→ Total Surface Area of Right Circular Cylinder = 44/7 × 170

→ Total Surface Area of Right Circular Cylinder = 7480 / 170

[ ✒Total Surface Area of Right Circular Cylinder = 1068.57 Cm² ✒ ]


{ Therefore, Total Surface Area of Right Circular Cylinder is 1068.57 cm² }. ✍
