Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²
Answer:
6
Step-by-step explanation:
Arc length = radius * central angle
s = rθ
A circle is 2π radians, so 1/3 of that is 2/3 π.
Given that s = 12 and θ = 2/3 π:
12 = r (2/3 π)
r = 18/π
r ≈ 6
