Answer:

108 deg

Step-by-step explanation:

Since sides DB and CD are congruent, then opposite angles are congruent.

m<C = m<B = 36

m<B + m<C + m<D = 180

36 + 36 + m<D = 180

m<D = 108

Can someone help me find the volume please

umka2103 [35]

Answer:

See below.

Step-by-step explanation:

The figure is a cone. The formula for the volume of a cone is:

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

The radius is 4.8 and the height is 2.9. Substitute:

$V=\frac{1}{3}\pi (4.8)^2(2.9)$

Use a calculator:

$V\approx69.97\text{ km}^3$

And we're done!
