Given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.
<h3>What is the circumference of the discus?</h3>
Note that; a circumference is the perimeter of a circle or ellipse.
It is expressed as C = 2πr
Where r is the radius and π is the constant pi ( π = 3.14 )
Given that;
- Radius of the discus r = 11cm
- Circumference C = ?
C = 2πr
C = 2 × 3.14 × 11cm
C = 69.08cm
Therefore, given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.

The second one:
3^7 x 3^(86/10) x 3^(9/1000)
That is because when you multiply powers with the same base ( in this case they are all 3), you just leave the base as it is and add the exponents
so it is basically 3^(7 + 86/100 + 9/1000) which is 3^7.869
I think you would need 65 cups to get $55.25.
You should divide 55.25/0.85
If you are being serious it's 19
Answer:
y = -x + 1
Step-by-step explanation:
First, simplify -x+y=-6 to y = x - 6
Being perpendicular, then the x needs to be "flipped", making the slope y = -x
In order to have the slope go through (-4, 5), the line needs to intercept the y-axis at 1
Thus, the equation is
y = -x + 1
