If the radius of a circle is d, then the area is ___.
d
2d
d/2
d2
Area of a circle = π(radius)2 Given radius = d Thus area=πd2
The area of a circle is πd2, then the radius of the circle is ____.
The area of a circle is πd2 square units, then the radius of the circle is ___.
A line meets the co-ordinate axes in A & B, A circle is circumscribed about the triangle OAB. If d1 and d2 are the distances of the tangent to the circle at the origin O from the points A and B respectively the diameter of the circle is:
If (a−d)2 , a2 , (a+d)2 are in GP, then d2a2 equals to [a ≠ 0,d ≠ 0]
