Use function notation to represent the area of a circle whose circumference is 103 cm
Nataly_w [17]

Circumference of the circle =103 cm

i.e., C = 2 \pi r = 103

i.e., r = \frac{103}{2 \pi}


Area of the circle is given by

A = \pi r^2

A = \pi (\frac{103}{2 \pi})^2

A = \pi (\frac{10609}{4 \pi^2})

A =\frac{10609}{4 \pi}

Therefore, the area of the circle is: A =\frac{10609}{4 \pi}  cm^2
