Answer:
Step-by-step explanation:
8 / 200 = 4 / 100 = 0.04 ;
The formula for circumference is C= 2(pi)(r)^2. Because diameter is double the radius, and the diameter is 8 ft, the radius is 4 ft. So, plug that into the equation, and you get: C=2(pi)(4)^2. The answer is 32 pi ft. If the question asks for the exact answer, keep the pi as it is, but if it says to round, multiply 32 by pi and round.
Answer:
23.6 or A
Step-by-step explanation:
We have sin already. 8/20
We use inverse sin of 0.4 (8/20)
The answer of inverse sin is 23.57817848
or 23.6
Answer:
60°, arms 6
Step-by-step explanation:
let the total arms = n
total generated angles in a regular polygon is = (n-2)×180
now,
(n-2)×180 = 120 n
or, 180n - 360 =120n
or, 60n = 360
or, n = 6
