Question

Which choice best represents the area of a circle with a diameter of 16 cm. Use TT= 3.14A: 256 centimeters squaredB: 803.84 centimeters squaredC: 25.12 centimeters squaredD: 200.96 centimeters squared

Answer 1

the diameter of the circle is

D = 16 cm

so the radius is r = D/2 = 16/2 = 8cm

the area of the circle is,

`A=\pi* r^2`

put r = 8 and pi = 3.14

`\begin{gathered} A=3.14*8^2 \\ A=200.96\text{ cm\textasciicircum{}2} \end{gathered}`

thus the area of the circle is 200.96 centimetres squared.
