A circle is formed by taking hypotenuse of right triangle as diameter. Find area of the circle, if other sides of their triangle are 6 cm, 8 cm?
Answer & explanation
Correct answer: option 4
Diameter (AC) = \(\sqrt {AB^2 + BC^2}\)
= \(\sqrt {36 + 64}\)
= 10 cm
Radius = 5 cm
Area of circle = \(\pi \) r2
= \(\pi \)(25) = 78.57 cm2
