How do i find the circumference of a circle? If I use a 3 as an estimate of pie and the circle is 10 mm across

Answers

Answer 1

Answer: If you're using pie it would be

2* $\pi$ *5 because the radius is half of the diameter.

But since you're using three it's

2*3*5

If it helps remember: Twinkle twinkle little star, circumference equals 2 pi r

A circle has a sector with area 27pi and central angle of 120 degrees. What is the area of the circle

Answers

Answer:

81 π

Step-by-step explanation:

The total central angle for a circle is 360 degrees.

In the question the sector with angle 120 degrees has area 27π.

So the circle can be considered as a combination of 3 sectors having angle 120 degrees each. Refer to the figure below.

Thus area of the circle will be three times of the area of the sector.

Area = 3 × 27π = 81π

Answer:

Step-by-step explanation:

81pi

How do u do this? I need the answer ASAP

Answers

Angle x is 100 degrees because the opposite angle is 80 degrees and they must add up to 180 degrees.

Angle X is 100 degrees because when you are adding up to 180 degrees, subtract the angle you already know from 180 and you will have your answer. 100 degrees

Persons younger than 18 years old are not eligible to vote. Let a be age in years. Which inequality models this situation?

A.
a < 18 and a may be a negative number

B.
a < 18 and a must be a positive number

C.
a > 18 and a may be a negative number

D.
a > 18 and a must be a positive number

Answers

D because a has to be younger than 18 and it has to be positive because we are never a negative age. do you understand when i mean?

The answer is D because the age has to be greater than 18 (including 18 years as well.) When the age is either going to be 18 or greater, you can't go back down to negative numbers because you increase age by one each year, not minus numbers, or decimals. For example, you go 1 year, 2 years, 3 years, not 1 year, 0 years, -1 years. I hope you understand that but if not just tell me in the comments :)

What is the answer!!! 35.00 for a jacket. 10% discount 5% sales tax whats the final cost? PLEASE HELP ME

Answers

Firstly, you should find the discount that is taken off of the jacket, and then also find the sales tax.
As the discount is 10%, you simply have to divide 35 by 10. 35/10= 3.50.
Therefore, you need to subtract the 3.50 from the 35, which gives you 31.50. You've then got the 5% sales tax to add on, which is 3.50/2= 1.75, you've then got to add 1.75 to 31.50, which gives you 33.25.
However, if the sales tax is on the discounted price, then it will be 31.50/10= 3.15/2= 1.58, and you've then got to add this is to discount price, which is 31.50+1.58= 33.08

Hope this helps :)
