# Question help watch

1. Hiya,

For a) would it be that 48 + 110 = 158 then 180-158 = 22 and thus CDX = 22 as they are alternate?
2. Both triangles are equal so angle BXA also equals 110 so the angle BAX would be 22 because angles in a triangle equal 180. That means angle CDX also equals 22
3. Angle XCD is 48 because angles in the same segment are equal (bow-tie rule). Angles in a triangle equal 180 so 110+48= 158. 180-158=22
4. Thankyou and how would I solve b?
5. Also I have no idea how to solve this, why am I doing Higher Maths omg

What's the volume of the sphere in terms of r? What about the cylinder in terms of r and h?

Equate those two expressions and solve for h.
