Construct a circle foe class 7

1.	Construct a circle foe class 7
Answer» ANSWER: Step-by-step explanation: Hint: We will draw the circle using a compass. First, we will draw its diameter using a scale. Then, we will construct a PERPENDICULAR bisector at both ends of its diameter. These bisectors will be the tangents to the circle. Formulas used: We will use the formula 2(RADIUS)=diameter . Complete step-by-step answer: We know that the diameter of a circle is 2 times its radius. Now, we will calculate the radius of the circle. 2r=7 Dividing both side by 2, we get ⇒r=72⇒r=3.5 We have CALCULATED that the radius of the circle is 3.5 CM First, we will draw a circle of radius 3.5 cm. We will take a scale and open the compass 3.5 cm. We will choose a centre for the circle and construct it. We will also draw the diameter of the circle by making a line passing through its centre:

Step-by-step explanation:

Hint: We will draw the circle using a compass. First, we will draw its diameter using a scale. Then, we will construct a PERPENDICULAR bisector at both ends of its diameter. These bisectors will be the tangents to the circle.

Formulas used:

We will use the formula 2(RADIUS)=diameter

Complete step-by-step answer:

We know that the diameter of a circle is 2 times its radius.

Now, we will calculate the radius of the circle.

2r=7

Dividing both side by 2, we get

⇒r=72⇒r=3.5

We have CALCULATED that the radius of the circle is 3.5 CM

First, we will draw a circle of radius 3.5 cm. We will take a scale and open the compass 3.5 cm. We will choose a centre for the circle and construct it. We will also draw the diameter of the circle by making a line passing through its centre:
