I believe your answer is D

It's the formula of the volume of a cone with equal lengths of radius and height.

Yes it's SAS
AD = CD (given)
BD = BD (common side )
but since it didn't say AC丄BD
it's no way to prove the angels r 90° :/
but as it already given AD= CD
so it's proven that it's an isosceles triangle
therefore
∠BAD = ∠BCD (base ∠s isos. ∆)
therefore it's SAS (side angel side)
Sure thing!
So if we look at the function, it is an exponential, meaning that it is a number to the power of x
The graph can be described by the equation
y = a^x
If we look at the graph, one of the points on the line is (2, 16), the x value is 2 and the y value is 16
If we consider this along with the function for the graph, we can say that
16 = a^2
Just solve this for a and you’ll have your answer :)
