Hello from MrBillDoesMath!

Answer:

Domain restriction: -3 <= x <= 0

Range restriction: -4 <= y <= 0

Discussion

These numbers came directly from the graph. I am assuming the endpoints such as x = -3 are included in the domain.

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{plum}\tt\bold{(B)}$ </h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

We know that :

$\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

So, let the diameter of this circle be x.

Which means :

$=\tt2 \times \pi \times r$

$=\tt 2 \times x \times \pi = 12\pi$

$=\tt 2x\pi = 12\pi$

$=\tt x = \frac{12}{2}$

$= \tt \: x = 6 \: m$

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎<em>Therefore, the correct option is (B)</em>

A wheel has a radius of 15 cm. Approximately how far does it travel in 4 revolutions?

ArbitrLikvidat [17]

Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D
