What will be the area of a circle if it’s radius is tripled

1 answer:

4 0

The circumference of a circle is equal to the diameter times pi. So, let's look at what happens if you double the radius of a circle -- say from 2 to 4. The area will go from 12.56 to 50.24. This means that it has quadrupled.

Equation giving the length of this rod at temperature is g = 0.000085t + 84.991075 cm.

What is temperature ?

A temperature is a unit used to represent voguishness or coolness on any of a number of scales, including Fahrenheit and Celsius.
According to temperature, heat energy will naturally move from a hotter( body with an advanced temperature) to a colder( body with a lower temperature)( one at a lower temperature).

Given that,

Temperature denoted by T

G - L = aL(t - T)

G = aLt + L(1 - aT)

Slope = aL

Intercept = L(1 - aT)

g = 0.000085t + 84.991075 cm

What is the solution to the system of equations below?

Burka [1]

Answer:

(x, y) = (-4, -15)

Step-by-step explanation:

You can equate the expressions for y and solve for x.

3/4x -12 = -4x -31

Adding 4x+12 gives ...

(4 3/4)x = -19

(19/4)x = -19

Multiplying by 4/19, we find ...

x = -4

Substituting that into the first equation, we can find y:

y = (3/4)(-4) -12 = -15

The solution is (x, y) = (-4, -15).

1. Write the equation of the line with y-intercept 3<br> and a slope of -2/3and graph it.

gtnhenbr [62]

Answer:

y= $\frac{-2}{3}$ +3

Step-by-step explanation:

The equation is y=mx+b

m is your slope

b is your y-intercept

The graph should cross the y-intercept on the y-axis 3 and be a negative slope (left to right diagonal) Place a point on y=3 go down 2 and then right 3
