Answer:
The length of minor arc AB is
π ft
Step-by-step explanation:
The formula of the length of an arc in a circle is L =
× 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle
∵ The radius of the circle is 4 ft
∴ r = 4
∵ ∠AOB is a central angle subtended by minor arc AB
∵ m∠AOB = 50°
∴ α = 50°
Substitute the values of r and α in the rule above
∵ L =
× 2π(4)
∴ L =
π
∴ The length of minor arc AB is
π ft
The answer to this is the second choice
Answer:
4.243
step by step explanation:
403, 892 rounded to the nearest thousand is 404,000.
The three is in the thousands place, and the 8 in the hundreds place tells us us to round up. The three becomes a 4 and everything behind it a 0. :)
