Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
Answer:
Two points, (0,4) & (8,5)
Step-by-step explanation:
In this equation, we can easily find the first point by looking at the +4 in this equation. This should automatically signal to you that the point is (0,4)
Now, we have to look at the 1/8x in the equation.
This 1/8 means that the slope is 1/8!
Now we use the slope and to rise/run to find our next point
We go up 1 from 4 (this is the rise) to get to 5 on the y-axis
Next, we go over 8 horizontally to get to 8 for your x-axis point.
So therefore, our next point is, (8,5)
You can use this rise/run system infinitely and is very useful
Well first off those numbers add up to 163.
A way to check this is to add 52 with 23 which is 75 then add 78 by 10 which is 88 now add 75 with 88 which is 163
