15 points !!!! Diameter Radius Area Circumference of 84mm
SSSSS [86.1K]

Answer:

lets \:  \:  \: find \:  \: the \:  \: radius \\  = 2\pi \: r \\  = 2\pi \: r = 84 \\  =  \frac{2\pi \: r}{2\pi }  =  \frac{84}{2\pi}  \\  = r = 13.37mm

lets \:  \:  \: find \:  \: the \:  \:  \: area \\  = \pi {r}^{2}  \\  = \pi \times  {13.37}^{2}  \\  = 561.55 {mm}^{2}

lets \:  \:  \: find \:  \:  \: the \:  \: diameter \\  = d = 2r \\  = d = 2 \times 13.37 \\  = d = 26.74mm
