The two circles shown above have radii of 8 in. and 4 in. What is the Circumference of the both?
1 answer:
Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches
Step-by-step explanation:
Radius of circle 1 = 8 inches
Radius of circle 2 = 4 inches
We need to find circumference of both circles.
The formula used to find the value of circumference is:
Finding Circumference of Circle 1:
Radius = 8 inches
π = 3.14
Putting values and finding circumference
Finding Circumference of Circle 2:
Radius = 4 inches
π = 3.14
Putting values and finding circumference
So, Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches

The equation for working out the slope of a linear line is: , where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do , which is just
when simplified.
Step-by-step explanation:
Given that,
A motor boat travels 60 miles down a river in 3 hours but takes 5 hours to return upstream,
We know that,
Speed = distance/time
The rate while moving downstream
The rate while moving upstream
The rate of the boat in still water is the average of these:
The rate of the current is the difference between the boat speed and actual speed = 16 mph - 12 mph = 4 mph
Hence, this is the required solution.
