How do i get the circumference and area of a circle

Mathematics
1 answer:
Annette [7]3 years ago
7 0
Circumference: C=2pir
C stands for circumference. pi is 3.14... and r is the radius.
of course, you can always do, C=pid. where d is diameter because the radius is half the diameter
Area: A=pir^2
A stands for the Area, pi stands for 3.14... r stands for radius, and the little ^2 is the equation squared. The way to solve that is square the radius and then multiply what you got from squaring the radius by pi.

 DO NOT replace radius with the diameter when trying to find the Area

Graph 18x-6y=-30 indentify the slope and y intercept
CaHeK987 [17]

Answer:

y=3x+5

Step-by-step explanation:

  1. start by putting 18x on the other side of the equation

- to do this you have to subtract, so it will be -18x now

2. now you have -6y=-18x-30

3. now you need to divide -6 by -18 and -30 on the other side to get y by itself

4. this will leave you with y=3x+5 because 6 divided by 18 is three and 30 divided by 6 is five.

I hope this helps!!

Urgent! <br>Quadrilateral ABCD is inscribed in the circle. What is the measure of angle C?​
AnnyKZ [126]

Answer: 92

Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.

First solve for x:

2x+34=180

x = 73

Then, solve for c

3x + 49 + c = 360

3(73) + 49 + c = 360

268 + c = 360

c = 92

Kyndal wants to buy a lamp that
fenix001 [56]

Answer:

$39.36

Step-by-step explanation:

Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82

82x0.8= 65.6

Since there is a additional 40% off multiply by 0.4 to get the discount amount

65.6x0.4= 26.24

Subtract the discount from the price

65.6-26.24= 39.36

Factor f(x)=-8x^4-16x^2
guajiro [1.7K]

Answer:

8x^2(x^2-8)

Step-by-step explanation:

you find the lCM

the LCM of 16 and 8 is 8

the LCM of x^2 and x^4 is x^2

in all the LCM is 8x^2

8x^4/8x^2=x^2

you divide the numbers and subtract the powers of the variables

<h3>-16x^2/8x^2= -8 </h3><h3>the you put everything in a distribution form</h3><h3 />
