The radius of the base is 10 cm.

Solution:

Height of a cone = 15 cm

Volume of the cone = 1570 cm³

To find the radius of the base of the cone:

Volume of the cone = $\frac{1}{3}\pi r^2 h$

$$\Rightarrow \frac{1}{3}\pi r^2 h=1570$

$$\Rightarrow \frac{1}{3}\times\ 3.14\times r^2 \times 15=1570$

$$\Rightarrow\ 3.14\times r^2 \times 5=1570$

$$\Rightarrow\ 15.7\times r^2 =1570$

Divide by 15.7 on both side of the equation, we get

$$\Rightarrow r^2 =100$

Taking square root on both sides of the equation, we get

⇒ r = 10

Hence the radius of the base is 10 cm.

Answer:

$256cm^2$

Step-by-step explanation:

Calculate the area of the two triangles first: 6 * 16 = 96

Then the rectangle: 10 * 16 = 160

160 + 96 = 256
