Find the diameter of the circle whose circumference are 198cm

Step-by-step explanation:

Given,

Circumference ( C ) = 198 cm

Diameter ( d ) = ?

Now, let's find the diameter of the circle :

We have,

plug the values

⇒

Swap the sides of the equation

⇒

Divide both sides of the equation by 3.14

⇒

Calculate

⇒ cm

▪️

⇒The perimeter of a circle is called it's circumference. It is the total length of the curved line of the circle.

▪️

⇒It is the line segment that joins the center of a circle and any point on its circumference.

▪️

⇒A line segment that passes through the centre of a circle and joins ant two points on its circumference is called the diameter of the circle. The length of a diameter is two times radius.

Hope I helped!

Best regards!!

the answer is true.

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
