I believe the shirts are different (in color, in size, in style,...), is so then:
¹⁰C₆ = (10! )/( 6! )( 10-6) ! = 210 COMBBINATIONS
¹⁰C₆ = (10! )/( 6! )( 10-6) ! = 210 COMBBINATIONS

Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
Multiply both sides by 36
Divide both sides by 5π
