GarryVolchara [31]

Answer:

Why? You have it there. Anyways, here's the step=by step.

Step-by-step explanation:

The equation for the volume of a cylinder is

V= π × height × radius²

V=π × r² × h

What you'll do then is multiply

11.1 × 34.4² × 3.14

Type that in a calculator and boom, you got your answer!

The circumference of a circle is 22 cm.

valkas [14]

$\bf \: Circumference \: of \: a \: circle = 2\pi \: r$

$\implies22 = 2 \times \dfrac{22}{7} r$

$\implies22 = \dfrac{44}{7} \times r$

$\implies \: r = \dfrac{22 \times 7}{44}$

$\implies \boxed{ r = \dfrac{7}{2} }$

Now,

$\bf \: Area \: of \: circle = \pi {r}^{2}$

$\rightarrow \: \frac{22}{7} \times ({ \frac{7}{2}) }^{2}$

$\rightarrow \frac{22}{ \cancel7} \times \frac{ \cancel{49}}{4}$

$\rightarrow \: 22 \times \frac{7}{4}$

$\rightarrow \: 11 \times \frac{7}{2}$

$\rightarrow \frac{77}{2}$

$\rightarrow \: 38.5 \: cm {}^{2}$

Area of rectangle = 38.5 cm².

aniked [119]

Answer:0.625

Step-by-step explanation:

Given

There are two coins one is fair and another is bent

Probability of getting a head on fair coin is 0.5

Probability of getting a head on bent coin is 0.75

If both coins are tossed once

probability of getting at least one of the coin will come up tails is

$P=1-P(both\ heads)$

$P=1-0.5\times 0.75$

$P=1-0.375$

$P=0.625$
