Let me get your number
Answer:
central angle=18
arc length=2.5 π feet
area of a sector=31.25π square feet
Step-by-step explanation:
Given
wheel radius=25 feet
attached cars=20
Space between cars along the circumference of wheel= 360/20
=18
Finding arc length:
arc length= radius x angle(in radians)
angle in radian = 18 x π/180 = 0.1π radians
arc length = 25 x 0.1π
=2.5π feet
Area of the circle = πr^2
Area of the circle = π(25)^2
Area of the circle = 625π square feet.
As the ratio of the central angle to the full circle angle is proportional to the area of the sector to the complete circle:
central angle/360=area of sector/area of circle
Area of sector= area of circle x 18/360
= 625π(1/20)
=31.25π !
Answer:
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
<em>Lacey's mom makes her a birthday cake in the shape of an "L" . Lacey loves frosting, so her mom covers the entire outside of the cake in frosting, even the bottom of the cake.
</em>
<em>How much space does Lacey's mom cover in frosting?
</em>
My answer:
As we know that the surface area of the the cake is made up of rectangles. The formula for find the area of a rectangle is A = lw
- The area of rectangle ABCD: 4*2 = 8
- The area of rectangle ADFE : 12*2 = 24
- The area of rectangle TJVS : 4*2 = 8
- The area of rectangle ESFV :9*2 = 18
- The area of rectangle HTJG: 5*2 = 10
- The area of rectangle CBHG: 2*8 = 16
The area of CDEVGJ = ABHTFS
= 4*12 + 4*5
= 68
So the total area is: 68 +68 +16+10+18+8+24+8 = 220
Hope it will find you well
Answer:
Point S coordinates= (-4,5)
Step-by-step explanation:
If you would just move the point 5 PLACES TO THE RIGHT, you would get -4, 5, which is the correct answer.
