for part b I'm not sure how to do it
any hints on how to do it? I've tried using sine rule etc but I'm just guessing, and I'm pretty sure there is a more simple method.

In order to calculate the circumference of a circle in radians, you can use the formula C = 2πr, where C is the circumference and r is the radius of the circle. However, it is important to first convert the angle measure from degrees to radians by multiplying it by π/180.
Radians are used to measure angles in a circle and are especially useful in mathematical calculations involving trigonometric functions. They allow for more precise and efficient calculations compared to using degrees.
Radians are a unit of measurement for angles in a circle. It represents the length of the arc on the circumference of a circle, divided by the radius of the circle. In simpler terms, it is a way to measure angles based on the size of the circle.
To convert degrees to radians, you can use the formula x degrees = xπ/180 radians. For example, if you have an angle of 90 degrees, it would be equivalent to (90π/180) = π/2 radians.
Yes, there are several methods for calculating radians in a circle, such as using the arc length formula or the circumference formula. The most common method is to use the formula θ = s/r, where θ is the angle in radians, s is the arc length, and r is the radius of the circle.
