Answer: 10 chairs
Step-by-step explanation:
The circular stage will be treated as a circle.
The 78.5 feet surrounds the circle so this is the circumference.
You need to find the diameter because that is the distance across the circle.
Circumference = π * diameter
Diameter = Circumference / π
= 78.5 / 3.14
= 25 feet
The distance across the circle is 25 ft, the number of chairs that can fit is therefore:
= Distance / Width of chair
= 25 / 2.5
= 10 chairs
Answer:
a) centre angles are double the circumference
b) 60 degrees
c) 120 degrees
Step-by-step explanation:
for c) the opposite angles in a cyclic quadraleteral add to 180 so take 60 from 180 to get 120
45% of 27 = 12.15
so 12.15 would be it
