ANEK [815]

Answer:

h= 24

Step-by-step explanation:

$v = \pi {r}^{2} \frac{h}{3}$

$r = \frac{d}{2}$

$r = \frac{14}{2}$

r= 7

1230.88=3.14×7^2×h/3

1230.88= 153.86h/3

h=1230.88/153.86

h= 24

What is the simplified version of the fraction below? 24/30

Ratling [72]

Answer:

4/5

Step-by-step explanation:

The prime factorization of 24 is 2*2*2*3.

There prime factorization of 30 is 2*3*5.

They have 2*3 in common.

2*3=6.

So we can divide numerator (top) and denominator (bottom) by 6 and this will reduce the fraction into simplest form.

$\frac{24}{30}=\frac{24 \div 6}{30 \div 6}=\frac{4}{5}$
