Answer:

A. c = 0.31b

Step-by-step explanation:

$7.44 = 24 juice bottles

[Divide by 24 on both sides]

$0.31 = 1 juice bottle

The cost is equal to the amount per juice bottle times the number of juice bottles, so:

c = 0.31b

(A trick to use when you don't know the answer: If there are multiple answers with the same numbers but the decimal places are in different places, it is probably one of those answers.)

What is the area of the circle in terms of pi? 3.7 m is the diameter

Liono4ka [1.6K]

Area of a circle is :
$\pi {r}^{2}$
Where r is the radius.
To find r, you divide the diameter by 2
$\frac{3.7}{2} = 1.85$
Then,
$\pi {1.85}^{2} \\ = \frac{1369}{400} \pi \\ or \\ = 3.4225\pi$

The formula for the area of a circle is A = πr2, where A = area and r = radius.

BaLLatris [955]

The area of a circle with radius of 5 feet is 25π square feet

Step-by-step explanation:

The area of a circle is found out using the formula

$A = \pi r^2$

Here A is the area

r is the radius of the circle and

pi is a constant

given

Radius = r = 5

We have to find the area in terms of pi

So,

$A = \pi r^2\\Putting\ r=5\\A = \pi *(5)^2\\A = 25\pi\ square\ feet$

Hence,

The area of a circle with radius of 5 feet is 25π square feet

(30/ If the surface of a lake represents a plane, what geometric

beks73 [17]

Answer:

A point

Explanation:

The surface of a lake represents a plane because it extends in all directions at the same level. Imagine it as a quite surface, without imperfections, smooth and perfectly plane, it is a two-dimensional figure.

A fishing line that enters into the water, crossing the lake's surface, representes a line, which may be either perpendicular or leaned.

Thus the intersection of those two figures is a point.

A surface and a line that is not included in the plane and is not parallel to it will meet at a single point, which is what is represented by the situation stated.
