Answer:

AB = 5

Step-by-step explanation:

The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be  √3  times as long, and the side opposite the 90 degree angle will be twice as long.

In this case we just divide 10 by 2

Answer:

Angle

= (bigArc - smallArc)/2

What are the coordinates of the midpoint of the segment with endpoints at (-3, -4) and (5, 8)?
lord [1]

Answer:

(4, ``6)

Step-by-step explanation:

The midpoint formula is

((x sub 2 - x sub 1)/2, (y sub 2 -y sub 1)/2). As shown, its written like a coordinate

Your x sub 1 is the x-coordinate of your first coordinate pair, and the rest follow the same pattern.

So, (5-(-3)/2, 8-(-4)/2)

5-(-3)=5+3=8

8-(-4)=8+4=12

(8/2, 12/2)

(4,6)

Volume of Cylinders - Item 20987 Question 1 of 7
solmaris [256]

Answer:

approximately the radius is 5 cm

Step-by-step explanation:

The formula for Volume of a Cylinder is shown below:

Volume of a Cylinder:

V=\pi r^2 h

Where

V is the volume

r is the radius

h is the height

We know

V = 1728

h = 22

We substitute and find r:

V=\pi r^2 h\\1728= (3.14)r^2(22)\\1728=69.08r^2\\r^2=25.014\\r=\sqrt{25.014} \\r=5.001

So we can that approximately the radius is 5 cm
