Answer:

Step-by-step explanation:

$(\frac{5}{4} + (-\frac{1}{3})) \div (\frac{5}{4} - (-\frac{1}{3}))\\\\\frac{\frac{5}{4}+\left(-\frac{1}{3}\right)}{\frac{5}{4}-\left(-\frac{1}{3}\right)}\\\\\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a\\=\frac{\frac{5}{4}-\frac{1}{3}}{\frac{5}{4}+\frac{1}{3}}\\\\\mathrm{Join}\:\frac{5}{4}+\frac{1}{3}:\quad \frac{19}{12}\\\mathrm{Join}\:\frac{5}{4}-\frac{1}{3}:\quad \frac{11}{12}\\\\=\frac{\frac{11}{12}}{\frac{19}{12}}\\\\=\frac{11\times\:12}{12\times \:19}$

Find the volume in cm^3 of a right circular cylinder with a radius of 10 cm and height of 14 cm

yawa3891 [41]

4398.22 cm³ the volume of cylinder.

What is volume of cylinder?

'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
The unit of volume is in cubic units such as m3, cm3, in3 etc.

Given,

Height of cylinder = 14 cm

radius of cylinder = 10 cm

Now using formula volume of the cylinder = π r² h

put value in formula,

3.14 × 10× 10 × 14 = 4398.22 cm³

Therefore, 4398.22 cm³ the volume of cylinder.
