Answer: 3.25 m
Step-by-step explanation:
as a tangency and a radius make a right angle, we can use Pythagoras.
c² = a² + b²
(r + 2)² = r² + 3²
r² + 4r + 4 = r² + 9
4r = 5
r = 1.25 m
so the official is standing 1.25 + 2 = 3.25 m from the center of the circle
This makes sense as a standard discus throwing circle is 2.5 m dia.
Step-by-step explanation:
Density (g/cm cubed) = Mass (g) / Volume (cm cubed)
So:
Density = 200g / 20cm cubed
Density = 10g/cm cubed
