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

Angles 1 and 2 are linear, meaning that they are supplementary, or add up to 180 degrees. We already know that angle 1 = 72 degrees. So, to find angle 2, take 180 and subtract 72 from it to get: 180 - 172 = 108 degrees. The answer is B.
Answer: no it not bigger because 30 is bigger than 10
Step-by-step explanation:
Answer:
26.6667 minutes or 0.444 hours per activity.
Step-by-step explanation:
If he spent an equal amount of time on each activity, then it would have to be divided equally: 4hours/9
In minutes:
4 x 60 = 240 minutes
240/9
26.6667 minutes per activity.
In Hours:
4/9
0.444 hours per activity.
Answer:
solutions to the absolute value inequality is 
Step-by-step explanation:
To find the solution of x absolute value of |x − 70| ≤ 3 will be written in the form of interval because the given fraction (x-70) is less than and equal to 3.
Now we add 70 on every part of the inequality.
So the solution to the absolute value inequality is .
