• B. PO and PQ are two _______ of the circle.
• C. OQ is the ___________ of the circle.
• D. The length of radius PO = ________ cm.
• E. The length of radius PQ = ________ cm.
• F. The length of the diameter = lengths of radii [PO + PQ]
  = 3.5 cm + 3.5 cm = _______ cm
• G. If the radius of the circle is $5cm$, what will its diameter be? _________
• H. If the diameter of the circle is $6cm$, what will its radius be? ______

Answer 1

The correct option is A P is the ______ of the circle.

In the given figure,

It cleared that

$OQ$ is the diameter of given circle and $PO$ and $PQ$ is radius of the circle.

$P$ is the centre of circle.

Part (A)

$P$ is the centre of the circle.

Part (B)

$PO$ and $PQ$ are two radius of the circle.

Part (C)

$OQ$ is the diameter of the circle.

Part (D)

The length of radius $PO=3.5cm$

Part (E)

The length of radius $PQ=3.5cm$

Part (F)

The length of diameter = lengths of radii $[PO+PQ]=3.5+3.5=7cm$

Part (G)

If the radius of the circle is $5cm$, then the diameter is $10cm$

Part (H)

If diameter of the circle is $6cm$, then the radius is $3cm$.
