Find the surface area of a cylinder

Harrizon [31]

Find the surface area of a cylinder

whose radius is 5 cm and whose

height is 10 cm.

<h3>Given:-</h3>

$\bullet$ Radius of a cylinder (r) is 5 cm

$\bullet$ Height of a cylinder (h) is 10 cm

The surface area of a cylinder

<h2>Solution:-</h2>

We know the formula of surface area of a cylinder is –

<h2> ${ \boxed{\rm \red {2πr² \: + \: 2πrh}}}$ </h2>

So, putting the value of r = 5 cm and h = 10 cm we get,

2πr(r + h) = 2 × $\frac{22}{7}$ × 5(5 + 10)

= $\frac{220}{7}$ (5 + 10)

= $\frac{220}{7}$ × 15

= $\frac{220 \: × \: 15}{7}$

= $\frac{3300}{7}$

= 471.43 cm²

The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1

Gelneren [198K]

Answer: a. 0.9876

Step-by-step explanation:

Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.

$\mu=12.3$ and $\sigma=0.1$

sample size : n= 25

Let x denotes the total body protein in healthy adult men in the sample.

Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-

$P(12.25$

∴ The correct answer is a. 0.9876

Find the circumference of the circle and round to the nearest tenth

VLD [36.1K]

Answer:

The circumference is 45.2yd

Step-by-step explanation:

Given

$d = 14.4$ --- diameter

Required

Determine the circumference

The circumference is calculated as:

$C =\pi d$

So, we have:

$C =\pi * 14.4$

Take pi a 3.14

$C =3.14 * 14.4$

$C =45.216$

Approximate

$C =45.2yd$
