Question

the hight of a cone is 15cm . if its volumr is 1570cm³ , find the radius of the base pie=3.14​

Answer 1

Answer:

this is the ans..........

Answer 2

Answer:

Radius = 10 cm

Step-by-step explanation:

Volume of a cone:

$V= \frac{\pi .r^2.h}{3} \\\\1570= 3.14*15*\frac{r^2}{3} \\\\1570= 15.7*r^2\\\\\frac{1570}{15.7} =\frac{15.7*r^2}{15.7} \\\\100= r^2\\\\\sqrt{100} =\sqrt{r^2}\\\\10=r$
