Answer 1

Answer:

$\pink{\boxed{\sf Given }}$

Height of cone→15cm

Volume of cone→1570cm³

$\pink{\boxed{\sf To\:find }}$

Radius of cone=?cm

Volume of Cone$\huge\green{\boxed{\sf </p><p> \frac{1}{3} \times \pi \times r {}^{2} \times h</p><p> }}$

Now put the values

$→</p><p> \frac{1}{3} \times \: 3.14 \times r {}^{2} \times 15$

Now this is equal to :

$1570 \times 3 = 3.14 \times 15 \times r {}^{2} \\ \frac{4710}{3.14 \times 15} = r {}^{2} \\ \\ 100 = r {}^{2} \\ r = \sqrt{100} \: \: cm \\ r = 10cm$

Radius →10cm

$\huge\red{\boxed{\sf Radius=</p><p>10cm</p><p>}}$
