Q. Circle O shown below has a radius of 26 inches. Find, to the nearest tenth of a degree, the measure of the angle, x, that forms an arc whose length is 44 inches.Answer: □∘
Use Arc Length Formula: To find the measure of angle x that corresponds to an arc length of 44 inches on a circle with a radius of 26 inches, we can use the formula for arc length: arclength=r×θ, where r is the radius and θ is the angle in radians.
Convert Radians to Degrees: First, we need to convert the angle from radians to degrees since the question asks for the answer in degrees. The conversion factor is π180 degrees per radian.
Solve for Theta: We can rearrange the arc length formula to solve for θ in radians: θ=rarclength.
Substitute Values: Substitute the given values into the formula: θ=26inches44inches.
Calculate Radians: Calculate the value of θ in radians: θ=2644≈1.6923 radians.
Convert to Degrees: Now convert θ from radians to degrees: θ×π180≈1.6923×π180≈96.9231 degrees.
Round to Nearest Tenth: Round the answer to the nearest tenth of a degree: θ≈96.9 degrees.
