Many objects in our daily life in round or circular shape, like a ball, wheel, bangle, clock, etc. Geometrically such objects are called a circle or sphere in two dimensional and three …

Answer: A circle’s perimeter is called the circumference. The symbol of the circumference is C. One can calculate by making use of the formula PZi x diameter, or 3.14 x d = C. Question 3: …

We know the formula, circumference = πd So, d = 2 cm, π = 3.14 Circumference of the circle =3.14×2 = 6.28 cm Was this answer helpful?

Given: A circle with centre O and diameter AB. Let PQ be the tangent at point A & Rs be the point B.

In figure AB is a diameter of a circle with centre O and AT is a tangent. If ∠AOQ =58∘, find ∠AT Q.

If the diameter of a circle is 10cm, then find the radius of the circle.

Answer: Usually, we can define pi as the ratio of the circumference of a circle to its diameter, hence the circumference of a circle is pi times the diameter, or 2 pi times the radius. So, this …

Let AB diameter of a given circle, and let P Q and RS be the tangents lines drawn to the circle at points A and B respectively.

Draw a circle with center A and radius 5 cm. Draw any one of the diameters. With same center A, draw another circle with radius 3 cm. Draw any one of the diameters for this circle too.

P QRS is a diameter of a circle of radius 6cm. The lengths P Q,QR and RS are equal. Semicircles are drawn on P Q and QS as diameters, as shown in the figure. Find the ...
