## anonymous one year ago A circular sundial has a circumference of 32􏰈 inches. What is the area of the sundial?

1. Photon336

$A = pir ^{2}$ we know that our circumference is 32 inches so we must find the radius to find the area. $C = 2pir$ $\frac{ c }{ 2\pi } = r$ $\frac{ 32 inches }{ 2\pi } = radius$

ok @frebrezze let me modify my answer

4. Photon336

$\frac{ 32\pi }{ 2\pi } = 16 inches = r$

5. Photon336

now $a = pir ^{2}$ $\pi*(16)^{2} = 256\pi$

does this make sense? @frebrezze ?

Thank you!!! sorry for typing it wrong and yes
