I believe it is 9pi because it is addition so it would be like this: pi + pi + pi + pi + pi + pi + pi + pi + pi= 9pi

The answer is 9pi, because pi+pi=2pi and when u add it will get 10pi but u subtract it by one
hope this helps!!

What is the curved surface area of a cylinder with the circumference of 4 and height of 6

Vera_Pavlovna [14]

The curved surface area of a cylinder is 24cm²

Given the following data;

Base circumference = 4 cm

Height = 6 cm

<h3>How to find the curved surface area of a cylinder?</h3>

Suppose that:

Radius of the considered cylinder = 'r' units

Height of the considered cylinder = 'h' units

Then, the curved surface area of that cylinder is 2πr h

To find the curved surface area (CSA) of the cylinder we have;

CSA of a cylinder = 2πrh

But 2πr = 4 cm

Now Substituting the values into the equation, we have,

CSA of a cylinder = 6 x 4

CSA of a cylinder = 24 cm²

Hence, The curved surface area of a cylinder is 24cm²

The equation for line p can be written as y= – 5/4 x–6. Line q includes the point (5, – 8) and is parallel to line p. What is th

Elden [556K]

Answer:

y = -(5/4)x - (1 3/4)

Step-by-step explanation:

A line parallel to y= -(5/4)x - 6 will have the same slope, -(5/4), but a different value for the y-intercept, which is -6 in this equation. This means we can write:

y = -(5/4)x + b

As klong a b is not -6, the line will be parallel. But we are told that point (5,-8) must be on the new line. That means we need to select a value of b to make that happen. By shifting b, we can move the straight line up or down. To move it so that it goes through (5,8), enter that point in the equation and solve for b:

y = -(5/4)x + b

-8 = -(5/4)*5 + b for (5,-8)

-8 = -(25/4) + b

b = -8 + (25/4)

b = -(32/4)+(25/4)

b = -(7/4) or - 1 3/4

The parallel line that goes through (5,-8) is y = -(5/4)x - 2
