Question

I will give the brainiest answer

Answer 1

Answer:

289 units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Here C = 907.46 , thus

907.46 = πd ( divide both sides by π )

d = $\frac{907.46}{\pi }$ ≈ 289 units ( nearest whole number )

Answer 2

Answer:

$d = 288.84 \: \: \: units$

Step-by-step explanation:

Using the formula

$c = 2\pi \: r$

Solving for r

$r = \frac{c}{2\pi} = \frac{907.46}{2\pi} \\ = 144.42674$

Now lets find the diameter

$d = 2r \\ d = 2 \times 144.42 \\ d = 288.84 \: units$

hope this helps
