Answer:

it would have twice the area of one circle because the radius would double therefore the inside/area would double

Answer:

No

Step-by-step explanation:

no!

Two circles of radius r

= 2(π)(r^2)

= 2π r^2

one circle of radius 2r

= π(2r)^2

= 4π r^2

use an example, eg. r = 3

two circles with r = 3

= 2π(3^2) = 18π

one circle with radius 6

= π(6^2)

= 36π

notice the singe large circle is twice the area of the two smaller ones

Can someone help me to find length CD
uysha [10]

Answer:

CD = 3.602019190339

Step-by-step explanation:

CD = DA - CA

DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507

BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278

CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168

Then

CD = 16.355388523507 - 12.753369333168 = 3.602019190339

A 2.5​ ft wide circular track for a camera dolly is set up for a movie scene. The two rails of the track form concentric circles
Deffense [45]

Answer:

15.71 ft

Step-by-step explanation:

Given that:

width of the circular track = 2.5ft

Suppose the radius of the inner circle is 57 ft since it is not given

Then the radius of the outer circle = (2.5 + 57) ft = 59.5 ft

The circumference of a circle = 2πr

For inner circle now, the circumference = 2 × π × 57 ft

For inner circle now, the circumference = 358.14 ft

For the outer circle, the circumference = 2 × π × 59.5 ft

For the outer circle, the circumference = 373.85 ft

The difference between the circumference of the outer wheel from the inner wheel shows how farther does a wheel on the outer rail travel than a wheel on the inner rail of the track in one​ turn

∴

= ( 373.85 - 358.14 ) ft

= 15.71 ft
