What is the best approximation for the area of this circle?
butalik [34]

Area =113.0ft^2 . Correct option is D) 113.0 ft² .

<u>Step-by-step explanation:</u>

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = \pi r^2 , We have following parameters as

Radius = r = 6 ft\\\pi = 3.14\\Area= \pi r^2 = ?

So , Area of circle is

⇒ Area =\pi r^2

⇒ Area =(3.14) (6)^2

⇒ Area =(3.14) (36)^

⇒ Area =113.04ft^2

On Rounding off

⇒ Area =113.0ft^2

Therefore , Area =113.0ft^2 . Correct option is D) 113.0 ft² .

Which statement best describes (3 x 4 x6 = 3 x (4 x 6)
Ratling [72]

Answer:

The given statement is,

(3 * 4) * 6 = 3(4 * 6)

To find (3 * 4) * 6

(3 * 4) * 6 = 12 * 6 = 72

To find 3(4 * 6)

3(4 * 6) = 3 * 24 = 72

Step-by-step explanation:

The result of these two expression is same.

Therefore we can conclude that,

Therefore the correct answer is,

Which equation represents a line that passes through (4, left-parenthesis 4, StartFraction one-third EndFraction right-parenthes
Alina [70]

Answer:

y-\frac{1}{3}=\frac{3}{4}(x-4)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

In this problem we have

point\ (4,\frac{1}{3})

m=\frac{3}{4}

substitute the given values

y-\frac{1}{3}=\frac{3}{4}(x-4)

y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)
