From the diagram, we can see that the radius of the cone is 8cm and the height of the cone is 15cm. We then just plug these numbers into the formula and simplify:
The volume of the cone is approximately 1005.3096 cm^3. With 3 sig figs, this is 1010 cm^3.

Answer:
45cm^2
Step-by-step explanation:
split the shape into a triangle and rectangle between points FE. Count how many squares up on the rectangle = 2cm
squares across = 9cm
2cm x 9cm = 18cm^2
for the triangle across would be 9cm
hight would be 6cm
9cm x 6cm = 54cm/2 = 27cm^2
18cm^2 + 27cm^2 = 45cm^2
