$\bf \textit{total surface area of a cylinder}\\\\
S=2\pi r(h+r)~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=4\\
h=7
\end{cases}\implies S=2\pi (4)(7+4)
\\\\\\
S=8\pi (11)\implies S=88\pi$

Put in slope intercept form

LiRa [457]

These require you solve for y. Do that by subtracting the x-term, then dividing by the y-coefficient.

5. 3y = 7x -9
y = (7/3)x -3

6. 6y = -2x -3
y = (-2/6)x -3/6
y = (-1/3)x -1/2

7. 8y = 2x + 12
y = (1/4)x +3/2

Answer:

750 mm²

Step-by-step explanation:

<h3>Area of triangle:</h3>

To find the area of the triangle, multiply the base and height and then divide the result by 2.

$\sf \boxed{\bf Area \ of \ triangle = \dfrac{1}{2}*base *height}$
