Circle O shown below has a radius of 8 inches. Find, to the nearest tenth, the radian measure of the angle, x, that forms an arc whose length is 12 inches.Answer: □ radians
Q. Circle O shown below has a radius of 8 inches. Find, to the nearest tenth, the radian measure of the angle, x, that forms an arc whose length is 12 inches.Answer: □ radians
Understand Relationship: Understand the relationship between arc length, radius, and angle in radians.The formula that relates arc length s, radius r, and 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=12 inches and the radius r=8 inches. We need to find the angle in radians, θ.So, we have 12=8θ.
Solve for θ: Solve for θ.To find θ, we divide both sides of the equation by 8.θ=812θ=1.5
Round Answer: Round the answer to the nearest tenth.The angle in radians is 1.5, which is already to the nearest tenth.
