circumference = 2</span>πR = 2 × 6 × π = 12π cm
Answer:<em>r = d/t</em>
Step-by-step explanation:
1. If we are solving for <em>r, </em>we need to have <em>r</em> on one side of the equation.
2. Divide by t on both sides = d/t=r
2.5+105sin40 t -16 t^2 = 0
t = (-105sin(40) + sqrt(105^2sin^2(40)-4(-16)(2.5))) /2(2.5)
t = .235 seconds if i entered those right
