Answer: 791.28cm^2

Step-by-step explanation:

A=2\pi rh+2\pi r^2

We have the diameter, to calculate the radius, divide by 2.

12/2=6cm

height: 15cm

Plug in the formula.

A=2(3.14)(6cm)(15cm)+2(3.14)(6cm)^2\\A=565.20cm^2+226.08cm^2\\A=791.28cm^2

Write the equation of a line that has a slope of -3 and goes through the point (5,7).
ss7ja [257]

Answer:

The equation of the line would be D) y - 7 = -3(x -5)

Step-by-step explanation:

In order to find this, we must first start with the base form of point-slope form.

y - y1 = m(x - x1)

Now we put the slope in for m and the point in for (x1, y1)

y - 7 = -3(x - 5)

Answer:

<6

Step-by-step explanation:

Corresponding angles have the same matching corner when a transversal line crosses tow straight lines.

Thus, in the diagram given, the angle that has the same matching corner with <2 is the angle that corresponds to <2.

<6 has the same matching corner with <2.

Therefore, <6 corresponds with <2
