Question

Pg 8 number 5 and 6 PLZZZ HELP

Answer 1

Answer:

Part 5) $C=8\pi\ cm$

Part 6) The ratio between the circumference and diameter of a circle, is equal to the number π

Step-by-step explanation:

The questions in the attached figure

Part 5)

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

we have

$D=8\ cm$

substitute

$C=\pi (8)$

$C=8\pi\ cm$

Part 6) What is the ratio between the circumference and diameter of a circle?

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

so

The ratio between the circumference and diameter of a circle, is equal to divide the circumference by the diameter

$\frac{C}{D}=\frac{\pi D}{D}=\pi$
