Question

A circular sundial has a circumference of 32􏰈 inches. What is the area of the sundial?

Answer 1

\[A = pir ^{2}\]

we know that our circumference is 32 inches so we must find the radius to find the area.

\[C = 2pir\]

\[\frac{ c }{ 2\pi } = r \]

\[\frac{ 32 inches }{ 2\pi } = radius \]

Answer 2

Answer 3

ok @frebrezze let me modify my answer

Answer 4

\[\frac{ 32\pi }{ 2\pi } = 16 inches = r\]

Answer 5

now

\[a = pir ^{2}\]

\[\pi*(16)^{2} = 256\pi \]

Answer 6

does this make sense? @frebrezze ?
