Circle in rhombus

In the rhombus is inscribed circle. Contact points of touch divide the sides to parts of length 19 cm and 6 cm. Calculate the circle area.

Correct result:

S =  358.14 cm2

Solution:

a=19 cm b=6 cm  S=π a b=3.1416 19 6=358.14 cm2a=19 \ \text{cm} \ \\ b=6 \ \text{cm} \ \\ \ \\ S=\pi \cdot \ a \cdot \ b=3.1416 \cdot \ 19 \cdot \ 6=358.14 \ \text{cm}^2
