Answer: 5 cm



Explanation: The formula for the volume of a cylinder is pi (3.14 here) * r^2 * 3

Thus, we have 235.5=3.14r^2*3

Dividing both sides by 3 leaves us with 78.5=3.14r^2

Dividing both sides by 3.14 gives us 25=r^2

To solve the equation, we take the sqrt of both sides and we find that r is 5 cm.

Answer:

5cm

Step-by-step explanation:

r=\sqrt{\frac{V}{\pi h} } \\=\sqrt{\frac{225.5}{\pi *3} } \\=5cm

What is the slope of the line represented by the points in the table?
kotykmax [81]

To find the slope(m) of the line, you can use the slope formula:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

and plug in 2 points.

You can use any of the points, I will be using the points (0, -0.25) and (1, -0.2)

m = \frac{y_{2}-y_{1}}{y_{2}-x_{1}}

m = \frac{-0.2 - (-0.25)}{1-0}

m = \frac{-0.2 + 0.25}{1-0}

m = \frac{0.05}{1}


m = 0.05  (The last answer)

lina2011 [118]

Answer with explanation:

Properties of Rectangle

1. Opposite sides are equal and parallel.

2. Diagonals are equal and bisect each other.

3. Adjacent Sides are Perpendicular to each other.

→If two lines are parallel their slopes are equal and if two Lines are perpendicular, their product of slopes is -1.

→A Rectangle is a Quadrilateral also.

→Adjacent sides are perpendicular ,so , their slopes can't be equal.Product of their slopes should be equal to ,-1.

⇒Slope of AB × Slope of BC = -1

⇒Also, Slope of AB × Slope of BC = -1

Slope of AB × Slope of AD = -1

⇒ Slope of AD × Slope of CD = -1

Slope of CB × Slope of CD = -1

Option B And Option C

are statement which proves that polygon ABCD is not a rectangle.
