Step-by-step explanation:

A semicircle is a half circle. That means a semicircle will have half of the area of a circle. You might think that means it will have half the perimeter of a circle, but that is not true.

To make a semicircle, take any diameter of the circle. Remove one half of the circle along that diameter. You have a semicircle (half of a circle).

A semicircle is half the circumference of a full circle plus the diameter of a cricle,

What can be used to determine the length of segment AB?
Vikki [24]

It depends on what you mean by "what can be used", you can use a protractor or ruler since it's a line segment. OR you can use the formula a^ + b^ = c^ to find out all the measurements.......

If you still can't find it, then, you can try to find the other measurements around that specific line segments. And it DEPENDS on what you choose to find the length of this segment.

( There's no picture on my screen, so I'm guessing that you didn't put any.. )

Well, I hope this can help you :3

STAY SAFE!! :)

Ms.Lamberson got a new puppy abd weighed it in September and October in September the Puppy Weighed9 and one Fourth pounds In Oc
ddd [48]

Answer: The puppy was 2.25\ lb havier in October that it was in September.

Step-by-step explanation:

You need to make the conversion from mixed numbers to decimal numbers. To do it, divide the numerator of the fraction by the denominator add the result to whole part number:

9\frac{1}{4}=9+0.25=9.25\\\\11\frac{1}{2}=11+0.5=11.5

The weight of the puppy in September was:

w_1=9.25\ lb

And its weight in October was:

w_2=11.5\ lb

Subtract its weight in September from its weight in October in order to find how much heavier the puppy was in October than it was in September:

w_2-w_1=11.5\ lb-9.25\ lb=2.25\ lb

What is the volume of the composite figure?
sertanlavr [38]

Look at the picture.

We have 3 cuboids. The formula of a volume of a cuboid is:

V = Length × Width ×  Height = lwh

The cuboid 1 are congruent to the cuboid 2.

<h2>1&2</h2>

l = 9 in, w = 10 in, h = 10 in

V = (9)(10)(10) = 900 in³

<h2>3</h2>

l = 6 in, w = 10 in, h = 10 in

V = (6)(10)(10) = 600 in³

The volume of the composite prism:

V = 2(900) + 600 = 1800 + 600 = 2400 in³
