# NAME THAT CIRCLE PARTS WORKSHEET ANSWER

## About "Name that circle parts worksheet answers"

Name that circle parts worksheet answers :

Here we are going to see some practice questions on name the circle parts.

Question 1 :

The _______ of a circle is the distance from the centre to the circumference.

(A) sector

(B) segment

(C) diameters

(D) radius

Solution :

The distance between the center point and a point on a boundary line is known as radius.

Hence the correct answer is radius.

Question 2 :

The relation between radius and diameter of a circle is ______

(A) radius = 2 × diameters

(B) radius = diameter + 2

(C) diameter = radius + 2

(D) diameter = 2 (radius)

Solution :

The distance between the center point and a point on a boundary line is known as radius.

The length of the line segment passing through the centre of the circle is known diameter. Half of the diameter is called radius.

So, the correct answer for the above question is diameter = 2 (radius).

Question 3 :

The longest chord of a circle is

(A) radius

(B) secant

(C) diameter

(D) tangent

Solution :

A segment of a straight line joining two points on a circle is called a chord; a chord that passes through the center of the circle is called a diameter.

Hence the correct answer is diameter.

Question 4 :

Area of a semicircle is ________ times the area of the circle.

(A) two

(B) four

(C) one-half

(D) one-quarter

Solution :

Two semicircles will create a whole circle. So area of semicircle is one half of the area of circle.

Question 5 :

The line segment that joins the centre of a circle to any point on the circle is called

(A) Diameter

(B) Radius

(C) Chord

(D) None

Solution :

Since the line segment that joins the center of the circle to any point on the circle, it is called as radius. If it will connect any two points on the boundary line,then we have to call it as diameter.

Question 6 :

A line segment joining any two points on the circle is called

(A) Diameter

(B) Radius

(C) Chord

(D) None

Solution :

A line segment joining any two points on the circle is called chord.

Question 7 :

A chord passing through the centre is called

(A) Diameter

(B) Radius

(C) Chord

(D) None

Solution :

A chord passing through the centre is called diameter and it is the longest chord.

Question 8 :

The diameter of a circle is 1 m then its radius is

(A) 100 cm

(B) 50 cm

(C) 20 cm

(D) 10 cm

Solution :

Radius  =  Diameter/2  =  1/2  =  0.5 m

Since the answer is in unit of cm, we have to convert meter into cm. For that we have to multiply 0.5 by 100.

0.5(100) = 50 cm

Hence the correct answer is 50 cm. After having gone through the stuff given above, we hope that the students would have understood "Name that circle parts worksheet answers".
