GUYS I NEED HELP ASAP!!! Help me solve ?

Mathematics
1 answer:
Shalnov [3]3 years ago
8 0

Solution:

$h=\frac{ A-2\pi r^2}{2\pi r }

Given data:

A=2\pi r^2+2\pi r h

Let us determine what is h using given A.

A=2\pi r^2+2\pi r h

Subtract 2\pi r^2 on both sides of the expression.

⇒ A-2\pi r^2=2\pi r^2+2\pi r h-2\pi r^2

⇒ A-2\pi r^2=2\pi r^2-2\pi r^2+2\pi r h

⇒ A-2\pi r^2=2\pi r h

Divide both sides of the expression by 2\pi r.

$\frac{ A-2\pi r^2}{2\pi r }=\frac{2\pi rh }{2\pi r }

$\frac{ A-2\pi r^2}{2\pi r }=h

$h=\frac{ A-2\pi r^2}{2\pi r }

Option C is the correct answer.

Hence $h=\frac{ A-2\pi r^2}{2\pi r }.

Hey so I'm a 15 year old in Geometry HN and I have my SOL tomorrow, (baisaclly state testing) I've been stuffy for weeks now yet
Digiron [165]

Answer:

2: 86

3:64

4: 77

6: 3

7:12

8: O=110 X:110

Step-by-step explanation:

Number 2 shows what is called a central angle. Central Angles are equivalent to the ark length

Number 3 shows an Inscribed angle. These angles are half of the ark but in your question, it is twice the angle measurement

Number 4 you want to divide the ark length by two when the angle is not given. And when the angle is given you want to mutilate by two

Number 6 is Overlapping Ark which means they are both congruent to each other because the ark is equivalent to each other.

Number 7 is x=12 because 5x+12 is twice the measure of 3x

Number 8 o=110 because a circle has 360 degrees so you want to add them up and then subtract that from 360. x is also 110 degrees because it is a central angle, which is the same amount of degrees as the ark length.
