          What is the circumference of the circle? (Its radius is 5 ft)

\diamond\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond

The distance from the tetherball pole to the edge of the circle is the radius of the circle; we're given that it's 5 feet (ft).

We're asked to find the circumference of the circle, which can be found using the following formula:-

❖  \sf{C=2\pi r}

<u>Where:-</u>

  • C=circumference
  • π=pi (3.14...)
  • r=radius

Substitute 5 for r:-

\sf{C=2\pi (5)}

On simplification,

\sf{C=10\pi}

On further simplification,

\sf{C=31.4\:feet}

So we conclude that the right option is:-

\checkmark\dashrightarrow\bigstar\boxed{\boxed{\bold{Option\:E}}}\bigstar\dashleftarrow\checkmark

<h3>Good luck.</h3>

Answer:

\huge\boxed{\bf\:E) \:  \: 31.4 \: \:feet}

Step-by-step explanation:

Since the tetherball is in the centre of the circle, any distance from it to the edge of the circle will be its radius. So, radius (r) = 5 ft.

Now, the formula for the cirumference of a circle = 2πr

Circumference of the circle

= 2πr

= 2 × 3.14 × 5                      [π = 3.14]

= 31.4 feet (option E)

(0,3) and (2,4) are on the line
solniwko [45]
Slope-intercept form is y = mx + b

The slope can be found by dividing y(2) - y(1) by x(2) - x(1).

4 - 3 = 1
2 - 0 = 2
m = 1/2

Since the first point has an x-coordinate of 0, the y-coordinate is the y-intercept of the line.

b = 3

Equation: y = 1/2x + 3

Find the volume of the pyramid. round to the nearest hundredth
hichkok12 [17]

Answer:

A. 17.35 mm³

Step-by-step explanation:

<u>Volume of a Pyramid</u>

V = \frac{1}{3}Bh

V ... volume

B ... area of base

h ... height

The base of this pyramid is a square. Area of a square is side times side.

B = 3.5 \times 3.5

Let's substitute in the formula.

V = \frac{1}{3}Bh\\\\V = \frac{1}{3}(3.5\times 3.5)(4.25)\\\\V = \frac{1}{3}(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3

Now let's round to the nearest hundredth.

V = 17.35 mm³
