The formula for the circumference of a circle is C = 2r. What is one-fourth of the circumference of a circle that measures 12 ce
Harman [31]

The formula of a circumference is:

C=2\pi r

r - radius

or

C=d\pi

d - diameter

We have d = 12cm. Substitute:

C=12\pi\ cm

One-fourth of the circumference:

\dfrac{1}{4}C=\dfrac{1}{4}\cdot12\pi=3\pi\ cm\approx3\cdot3.14=9.42\ cm

<h3>Answer:  9.42 cm.</h3>

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s
sweet-ann [11.9K]

Answer:

<em>V(t) = π(4cos πt -5sinπt) cm</em>

Step-by-step explanation:

Given the displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 4 sin πt + 5 cos πt, where t is measured in seconds, the average velocity of the body will be expressed as the change in displacement of thee particle with respect to time.

This is expressed mathematically as V = ds/dt

Differentiate the displacement function to get the velocity V

V = 4πcos πt + (-5πsin πt)

open the parenthesis

V = 4πcos πt - 5πsin πt

bring out the common factor

V = π(4cos πt -5sinπt)

<em>Hence the average velocity of the body during each time is expressed as </em>

<em>V(t) = π(4cos πt -5sinπt) cm</em>
