Question:

LAST ONE A new crop circle has appeared in Cool Town. It is a rather simple one. It consists of two concentric circles. The largest (outer) circle has a radius of fifty-two meters and the inner circle has a radius of thirty meters. What is the difference between the circumferences of the two circles?

Answers

238.23 meters.

Step-by-step explanation:

STEP 1

Find the circumferences of both circles!

Outer circle:

C = (radius*2)π

C = (52*2)π

C = 104*π

C = 326.725...

C ≈ 326. 73

Inner circle:

C = (radius*2)π

C = (30*2)π

C = 60*π

C = 188.495...

C = 188.50

STEP 2

Find the difference by subtracting.

outer circle - inner circle = difference

326. 73 - 188.50 = 238.23

238.23 meters.

138.16

Step-by-step explanation:

first you find the circumference of both of them. the big one is 52*2 *pi 52*2 is 104 then you multiply by pi 326.56

for the second circle you do 30*2*pi and get 188.4 then you subtract them and get 138.16

22\pi m

Step-by-step explanation:

Given:

Diameter is 9 m and the outer part of the circle is 2 m

To find: difference between the circumference of the outer circle and the circumference of the inner circle

Solution:

Diameter of inner circle = 9 m

Radius of the inner circle (r)  [tex]=\frac{9}{2}=4.5\,\,m[/tex]

Circumference of the inner circle [tex]=\pi r^2=\pi (4.5)^2[/tex]

As outer part of the circle is 2 m,

outer radius (R) = r + 2 = 4.5 + 2 = 6.5 m

Circumference of the outer circle [tex]=\pi R^2=\pi (6.5)^2[/tex]

So,

difference between the circumference of the outer circle and the circumference of the inner circle [tex]=\pi (6.5)^2-\pi (4.5)^2=\pi\left [ (6.5)^2-(4.5)^2 \right ]=\pi\left ( 42.25-20.25 \right )=22\pi[/tex] m

43.96 cm

≈ 44 cm

Step-by-step explanation:

Hi !

C₁ = 2π×r₁

C₂ = 2π×r₂

C₂ - C₁ = 2π×r₂ - 2π×r₁

= 2π(23cm - 16cm)

= 2×3.14×7

= 43.96 cm

≈ 44 cm

Good luck !

44 cm

Step-by-step explanation:

r = 16,R = 23;2πR - 2πr

2π(R - r)

2 ×22/7(23 -16)

2×22/7×(7)

2×22=44cm...

Answer

The circumference of a circle is the length of its side, the area is the amount of space within it.

Step-by-step explanation:

Step-by-step explanation:

The difference of the circumference of the pie container and pie is 6.3 inches.

Step-by-step explanation:

Given,

The radius of the pie container (R) = 9 in

The radius of the pie (r) = 8 in

To find the difference of the circumference of the pie container and pie.

Formula

The circumference of a circle = 2πr

Now,

The circumference of the pie container = 2×π×9 = 18π in

The circumference of the pie = 2×π×8 = 16π in

Hence,

The difference = 18π-16π = 2π = 6.28 = 6.3 inches (approx)

Circumference is all the way round the outside and area is all the space inside

Circumference=2[tex]\pi[/tex]r

Circumference of larger pizza: 2(3.14)(6) = 37.68
Circumference of medium size pizza: 2(3.14)(5) = 31.4

Difference is 37.68-31.4 = 6.28

The correct answer is answer choice 3 or C.
