उत्तर
Given: radius = 8 cm
Height = 6 cm
Area = ?
In a right angled triangle, the center of the circumference is the midpoint of the hypotenuse.
Hypotenuse `2xx`(radius of circumference) for a right triangle
=`2xx8`
=`16cm`
So, hypotenuse = 16 cm
Now, base = 16 cm and height = 6 cm
Area of the triangle=`1/2xxbasexxheight`
=`1/2xx16xx6`
=`48 cm^2`
