Circle O shown below has a radius of 11 inches. Find, to the nearest tenth, the radian measure of the angle, x, that forms an arc whose length is 26 inches.Answer: □ radians
Q. Circle O shown below has a radius of 11 inches. Find, to the nearest tenth, the radian measure of the angle, x, that forms an arc whose length is 26 inches.Answer: □ radians
Understand Relationship: Understand the relationship between arc length, radius, and central angle in radians. The formula that relates arc length s, radius r, and central angle in radians θ is s=rθ.
Plug in Values: Plug in the given values into the formula.We are given the arc length s=26 inches and the radius r=11 inches. We need to find the central angle in radians, θ.So, we have 26=11θ.
Solve for θ: Solve for θ.To find θ, we divide both sides of the equation by 11.θ=1126θ≈2.36363636...
Round Result: Round the result to the nearest tenth.Rounding θ to the nearest tenth gives us θ≈2.4 radians.
