Question

if the radius of the cylinder is 4 centimetre and height is 10 cm then total surface area is​

Answer 1

Answer:

Step-by-step explanation:

TSA of Cylinder=2πr(r+l)

r=4cm h=10cm

YSA=2(22/7)(4)(4+10)

=16(22)=352cm².

Answer 2

• Given

• Radius of the cylinder = 4 cm
• Height of the cylinder = 10 cm

• To find

• Total surface area of cylinder

• Solution

We have the values of the radius and height 9f the cylinder. So, by using formula -

★ Total surface area of cylinder = 2πr(h + r)

where,

• Take π = 22/7
• r = radius of the cylinder
• h = height of the cylinder

Substituting the values,

⟶ 2 × 22/7 × 4(10 + 4)

⟶ 44/7 × 4(14)

⟶ 44/7 × 56

⟶ 2464/7

⟶ 352 cm²

Therefore, the total surface area of the cylinder = 352 cm²

• Diameter = 2 × Radius
• Radius = Dimater/2
• Area of circle = πr²
• Volume of cylinder = πr²h
• Total surface area of cone = πrl + πr²h
• Curved surface area of cone = πrl
• Volume of cone = 1/3 πr²h
