<span>We know that the circumference of a circle is equal to pi times the diameter of the circle. Therefore, assuming this crater to be circular in shape, we can divide the circumference by pi, in this case 9033*7/22, yielding an answer of 2874.1 feet after rounding.</span>

A carnival ride is in the shape of a wheel with a radius of 25 feet. The wheel has 20 cars attached to the center of the wheel.
Vladimir79 [104]

Centre angle will be 360° as its totally a circle.

  • radius=r=25ft

Angle between two cars=360/20=18°

  • Arc length=L

\\ \sf\longmapsto L=\dfrac{\theta}{360}(2\pi r)

\\ \sf\longmapsto L=\dfrac{18}{360}(2\pi(25))

\\ \sf\longmapsto L=\dfrac{1}{20}(50\pi)

\\ \sf\longmapsto L=2.5\pi ft

Now

Area be A

\\ \sf\longmapsto A=\dfrac{1}{2}Lr^2

\\ \sf\longmapsto A=\dfrac{1}{2}(2.5\pi)(25)^2

\\ \sf\longmapsto A=625(2.5)\pi\dfrac{1}{2}

\\ \sf\longmapsto A=1562.5\pi/2

\\ \sf\longmapsto A=781\pi ft^2=

How many hours did I work if I worked 7 hours and 30 minutes a day, for 15 days?
baherus [9]

Answer:

112 hours and 50 mins

Step-by-step explanation:

Numbers of mins worked in a day = 7×60+30 =450 mins

Now number of mins worked in 15 days = 450×15

= 6750 mins

to convert mins into hours divide by 60

6750÷60 = 112.50

that means total number of hours worked in 15 days = 112 hours and 50 mins

mother = 40years

Step-by-step explanation:

salini = x \\ mother =8x \\ x + 5 = 1 \: of \: 8x \\  x + 5 = 2x \\ 5 = x

5 = x

then you equate the values of x
