Question

radius of cylinder is 1.5 cm height of cylinder is 6 cm find total surface area of a cylinder and covered surface area of a cylinder and volume of the cylinder​

Answer 1

Answer:

r is 1.5cm

h is 6cm

TSA 2pie r (r ➕ h)

TSA 2*22/7*1.5(1.5 ➕ 6)

49500/700

79.71cm2

Answer 2

Answer:

• CSA of cylinder = 56.52 cm² (Approx)
• TSA of cylinder = 70.65 cm² (Approx)
• Volume of cylinder = 42.39 cm³ (Approx)

Step-by-step explanation:

Given:

• Radius of cylinder = 1.5 cm
• Height of cylinder = 6 cm

To Find:

• TSA of cylinder
• CSA of cylinder
• Volume of cylinder

Now, first we will calculate its CSA,

⇒ CSA of cylinder = 2πrh

⇒ CSA of cylinder = 2 × 3.14 × 1.5 × 6

⇒ CSA of cylinder = 56.52 cm² (Approx)

$\rule{100}{1}$

Now, we will calculate its TSA,

⇒ TSA of cylinder = 2πr(h+r)

⇒ TSA of cylinder = 2 × 3.14 × 1.5(6 + 1.5)

⇒ TSA of cylinder = 2 × 3.14 × 1.5 × 7.5

⇒ TSA of cylinder = 70.65 cm² (Approx)

$\rule{100}{1}$

Now, we will calculate its volume,

⇒ Volume of cylinder = πr²h

⇒ Volume of cylinder = 3.14 × 1.5 × 1.5 × 6

⇒ Volume of cylinder = 42.39 cm³ (Approx)
