How do I find the circumference of a circle with an area of 48(pi symbol) square meters?

Question

After the 48 is the symbol for Pi. What does this mean?

Answer 1

We know that the area of a circle=pi*r^2
It is given that
pi*r^2=48 pi
Therefore,r^2=48
or r=sqrt 48=4sqrt3 units
The circumference of a circle is given by the formula 2pi*r
here r=4sqrt3
hence circumference
=2*3.14*4sqrt3
=2*3.14*4*1.732
=43.5078 units

Answer 2

The formula for the area of a circle is
A = π r²

The formula for the circumference of a circle is
C = 2 π r

The thing you need to know to get from A to C is r.

Solving A = π r² for r,
r = √(A/π)

Um… that means divide the value you have for the area by π, and whatever you get, take the square root. That’s r.

Now, to get C, multiply the value you get for r by 2 and multiply that by π.

Nothing complex... just a little bit of algebra.... you can do it.
Or you can wait for somebody to do it for you.

Answer 3

circumference= diameter times pi
area of a circle= pi times radius square
the radius is square root of 48, which is 6.93
now we have the radius, multiply it by 2 to find diameter.
6.93*2=13.86
then multiply by 3.14 and get 43.5 meters.
the circumference of this circle is 43.5 meters

Answer 4

A = πr² = 48π

πr² = 48π
r² = 48
r = sqrt(48)

C = 2πr
= 2πsqrt(48)
= 2πsqrt(16*3)
= 2πsqrt(16)sqrt(3)
= 2π * 4sqrt(3)
= 8πsqrt(3)

Which, evaluated on a calculator, is approximately 43.53 meters

Answer 5

Area = 48 pi = pi r^2

48 pi/pi=r^2

48 = r^2

r=6.928

Circumfurence=2*pi*r

circumperence =43.53meters

Answer 6

area = (Pi)(r^2) --- 1
Diameter = 2r --- 2

solve for r sub inot 2 then use Circumference formula to determine Circumference

Answer 7

π is a special number = 22/7 = 3.14
48 π = π r²
r = 6.93 m
C = 2 π r
C = 2 π [ 6.93 ] m
C = 43.5 m (to 1 decimal place)
