Answer:

The answer as a mixed number is $=15\frac{3}{4}.$

Step-by-step explanation:

Given:

5 1/4 ÷ 1/3.

Now, to solve as a mixed number in simplest form.

$5\frac{1}{4} \div \frac{1}{3}$

Now, changing the mixed fraction into improper:

$=\frac{21}{4} \div \frac{1}{3}$

So, to solve we change the division into multiplication.

Thus, R.H.S of the fraction will get reverse:

$=\frac{21}{4} \times \frac{3}{1}$

$=\frac{63}{4}$

Now, changing the improper fraction into mixed:

$=15\frac{3}{4} .$

Therefore, the answer as a mixed number is $=15\frac{3}{4} .$

Given V = 2πr2h, solve for h

Ipatiy [6.2K]

V=2*pi*r*2*h
V=(4*pi*r)*h
V/(4*pi*r)=h
so h=V/(4*pi*r)
