Surface area = PI x rL + PI x r^2

since the answer is in terms of PI, remove PI from the equation:

surface are = rl +r^2

r = 3 and l = 15

3*15 + 3^2 = 45 +9 = 54

answer is 54PI units^2

Answer is C

What is the equation of the line that passes through the point (5, -6) and has a<br> slope of – 3/5

Inessa [10]

Answer:

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1) \\$

where

m is the slope

( x1 , y1) is the point

From the question the point is (5, -6) and slope - 3/5

The equation of the line is

$y + 6 = - \frac{3}{5} (x - 5) \\ y + 6 = - \frac{3}{5} x + 3 \\ y = - \frac{6}{5} x + 3 - 6$

We have the final answer as

$y = - \frac{6}{5} x - 3 \\$

Hope this helps you
