Answer:

I need numbers to do a step by step

but the formula for the surface area of a cone.

Firstly, you work out the circle, pi x radius squared.

then you work out the cone

You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).

So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:

SA = πr2 + πrl

Is the function given by, f(x)={3x-2 if x≤3 , 10-x if x>3} continuous at x = 3?

Darya [45]

<h2>Answer:</h2>

yes

<h3>Step-by-step explanation:</h3>

This is a piecewise-defined function because it is defined by two or more equations over a specified domain is. The graph of this function is shown below. So this functions is continuous because its graph is a single unbroken curve. So the function is defined be the line 3x - 2 when x = 3 and the output here is y = 7
