Question

Find the total surface area of a right circular cylinder with radius 3cm and height 11cm

Answer 1

2xpiexrxh ➕ piexrxr

2 x ²²/7 x 3 x 11 ➕ ²²/7 x 3 x 3

235.71

Answer 2

Answer:

The correct answer will be -

The total surface area of the cylinder will be 263.76 cm².

Step-by-step explanation:

Given in the question -

• The radius of the cylinder is 3 cm.
• The height of the cylinder is 11 cm.

We have to find the total surface area of this right circular cylinder.

The total surface area of a cylinder is given by -

$2\pi rh+2\pi r^2$

Calculating -

$2\pi \times 3\times 11+2\pi \times 3^2$

Taking $\pi = 3.14$

$=2\times3.14 \times 3\times 11+2\times 3.14 \times 3^2\\\\= 207.24+56.52\\\\=263.76\ cm^2$

So the total surface area of the cylinder will be 263.76 cm².
