64 inches per bow * 9 bows = 576 inches. They want this in yards, so 576 inches is 48 feet which is 16 yards.
Answer:
Diameter = 8 ft
Step-by-step explanation:
To find diameter, we need to work backwards from the formula for circumference of a circle.
Circumference = 2πr
given that π = 3.14
Circumference = 2*3.14*r
25.12 = 2*3.14*r
25.12 = 6.28 * r
4 = r
Radius = 4
Formula for Diameter =
D = 2r
D = 2*4
D = 8
Diameter = 8
Lets Check
Circumference = 2 * 3.14 * 4
Circumference = 25.12
Correct

Answer:
<h2>84.78</h2>
Step-by-step explanation:
We have the area of a circle
The sector with a central angle of
Calculate, what part of 360° is an angle 120°:
The same part of an area of a circle is an area of a segment.
Therefore:
Use π ≈ 3.14
The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint
