This is VERY URGENT, so 50 points if you answer correctly!
Consider a circle with diameter of 10 cm. What is the circumference of the circle? What is the ratio of the circumference to the diameter?

The circumference is 31.43 cm

The ratio of the circumference to the diameter is equal to 3:1

Step-by-step explanation:

Thed formular for the circumference of a circle is 2r or d

where d = diameter and r = radius

if d = 10 cm, and = 3.143, then circumference of the circle can be given as

3.143*10 = 31.43 cm

The ratio of the circumference to the diameter can be given as 31.43:10

and that can be given as 3.143:1

or 3:1, for the nearest whole number

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
