Ivan and Tanya share £150 in the ration of 4:1

Zarrin [17]

Answer:

Money Ivan gets extra = 120 - 30 (or 3x) = 90

Step-by-step explanation:

Ivan = 4x

Tanya = 1x

Total = 150

4x + x = 150

5x = 150 ; x = 150 / 5 = 30

Ivan = 4x = 120

Tanya = 1x = 30

Money Ivan gets extra = 120 - 30 (or 3x) = 90

What is the volume of a sphere with a radius of 3 m, rounded to the nearest tenth

expeople1 [14]

<h3><u>Given</u>:-</h3>

$\rightarrow$ Radius(r) of sphere = 3m

$\rightarrow$ Volume of the sphere.

<h3><u>Formula Used</u>:-</h3>

$\rightarrow$ Volume of sphere = $\sf{\frac{4}{3}πr^3}$

<h3><u>Solution</u>:-</h3>

$\rightarrow$ Volume of sphere = $\sf{\frac{4}{3}πr^3}$ (putting the value of r(radius) from the above given and pie(π) = $\sf{\frac{22}{7}}$ )

$\rightarrow$ $\sf{=\frac{4}{3}×\frac{22}{7}×3^3}$

$\rightarrow$ $\sf{=\frac{4}{3}×\frac{22}{7}×27}$

$\rightarrow$ $\sf{=\frac{2,376}{21}}$

$\rightarrow$ $\sf{=113.14m^3}$

Therefore, the volume of the sphere $\sf{=113.14m^3}$ , which can be rounded off to it's nearest tenth as $\sf{113.1m^3}$
