Area of circle is 314 inches^2
Circumference of circle is 62.8 inches
Step-by-step explanation:
We need to find area and circumference of the circle whose diameter is 20 inches.
Area of circle
The formula used to find area of circle is:
value of π = 3.14
we know radius = diameter/2
So, radius = 20/2 = 2
Putting value of π and radius we get Area:
So, Area of circle is 314 inches^2
Circumference of Circle
The formula used to find circumference of circle is:
value of π = 3.14
diameter= 20
Putting value of π and diameter we get Circumference:
So, circumference of circle is 62.8 inches

Answer: $172.50
Step-by-step explanation: Method 1:
The original price of the item is $230.
The discount is 25%.
Let's find 25% of $230.
25% of $230 = 0.25 * $230 = $57.50
The discount amount is $57.50.
Now we subtract the amount of the discount from the original cost.
Sale price = $230 - $57.50 = $172.50
Method 2.
The original price is $230.
That means that $230 is 100% of the price since 100% of a thing means the entire thing.
Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.
The sale price is 75% of the original price.
Now we find 75% of $230.
75% of $230 = 0.75 * $230 = $172.50
If the graph is a straight line, then it is linear. And If the y values is the same. The power of each, x and y in the equation is one.
Answer:
question 9
92/11 or 8.36
Step-by-step explanation:
angle on straight line is 180
:. 10x+1 + 12x-5 = 180
collect like terms
10x+12x = 180+5-1
22x = 184
divide both sides by the coefficient of x
22x/22 = 180/22
:. x = 180/22(to d lowest form= 92/11)
or 8.36
