what is the circumferenceof a satellite dish which has a diameter of 21m
you do 2 times pie and radius
since you have the diameter then its 21 times pie . for futher info if your trying to find the area then you have to put it in radius form which is half the diameter is 10.5 and square it and times by pie.
To find the circumference of a circle, you need to multiply the diameter by π (pi). In this case, the diameter of the satellite dish is given as 21m.
So, to find the circumference, you calculate:
Circumference = 2πr
Since the diameter is given, you need to first find the radius by dividing the diameter by 2:
r = diameter/2 = 21m/2 = 10.5m
Now, substitute the radius value into the circumference formula:
Circumference = 2π(10.5m)
Simplifying further:
Circumference = 21πm
Therefore, the circumference of the satellite dish is 21πm.
