Calculating circle measures and solid volumes exactly, answers left in terms of π.

Author note — to cover

Fluency — circumference and area from an integer radius or diameter, answered as the coefficient of π (4 questions).
Arcs and sectors — arc lengths and sector areas for angles like 60°, 90° and 120° that leave exact fractions, plus one reversed to find the angle (4 questions).
Solids — volumes of cylinders, cones, pyramids and spheres with dimensions chosen so the thirds cancel, ending with a frustum by subtracting the missing cone (4 questions).
