Question

m, slant height 13 cm
The height of a cone is 15 cm. If its volume is 1570 cm’, find the radius of the base
(Use = 3.14)​

Answer 1

Answer:

r = 10 cm

Step-by-step explanation:

hope you get your answer

Answer 2

Answer:-

$↝\frac{1}{3} \times \rm \pi \times {r}^{2} \times h = 1570 \\ \\ ↝ \cancel\frac{1}{3} \times \rm 3.14 \times {r}^{2} \times \cancel{15} = 1570 \\ \\ ↝ 3.14\times {r}^{2} \times 5 = 1570 \\ \\↝ {r}^{2} = \frac{1570}{3.14 \times 5}\\ \\ ↝{r}^{2} = 100 \\ \\ ↝r = \sqrt{100} \\ \\↝ r = 10$

Hence, the radius of base is 10 cm.
