Whats the slope exactly lol you need a slope in order to make it into a point-slope form
Answer:
The outering is 11 cm so let's see what the Area is. We use the formula Area of a circle:
A = πr² = πd2/4
If:
Radius, r = 11 cm
Then:
Diameter, d = 22 cm
Circumference, C = 69.115038378975 cm
Area, A = 380.13271108436 cm²
now all we need to do is subtracts the inner circle Area.
If:
Radius, r = 9 cm
Then:
Diameter, d = 18 cm
Circumference, C = 56.548667764616 cm
Area, A = 254.46900494077 cm²
Thus: 380.13271108436 cm² - 254.46900494077 cm² =
125.6637061436 cm²
Step-by-step explanation:
You can find the simplest form by dividing both the numerator and denominator by the GCF (greatest common factor). 100 divides into 100 and 1,000 equally so that can be the GCF used to reduce the fraction into its simplest form.
![\frac{100/100}{1000/100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B100%2F100%7D%7B1000%2F100%7D%20%20)
![\frac{1}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B10%7D%20%20)
The simplest form is

Answer:
28:20
Step-by-step explanation:
you just multiply 5 by 4 because 20 divided by 4 is 5 and then multiply 7 by 4
Answer:
18$
Step-by-step explanation:
If you divide 12 by 2 then you will get 6 so 6 times 3=18.
sorry if I'm wrong.
