Circumference: C=2pir
C stands for circumference. pi is 3.14... and r is the radius.
of course, you can always do, C=pid. where d is diameter because the radius is half the diameter
Area: A=pir^2
A stands for the Area, pi stands for 3.14... r stands for radius, and the little ^2 is the equation squared. The way to solve that is square the radius and then multiply what you got from squaring the radius by pi.
DO NOT replace radius with the diameter when trying to find the Area
The volume of a cube with side length s is given by s^3.
s^3 = 512
s = cube root of 512 = 8.
The side length of the square is 8
Answer:
slope is -60
y- intercept is 300
y = -60x + 300
Step-by-step explanation:
Answer: y = - 6x + 3
Step-by-step explanation:
In the equation y=mx+b, The slope is m and the y-intercept is b. Plug in the numbers to get y=-6x+3.
Answer:
Slope - intercept form
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the point (2,-4) and slope 
Equation of the straight line passing through the point (x₁, y₁) and slope 'm'
y - y₁ = m( x-x₁ )
y - (-4) = 
( x-2)
⇒ 5( y+4) = 3(x-2)
⇒ 5 y +20 = 3x -6
⇒ 3x - 5 y -6-20 =0
⇒ 3 x -5y -26=0
<u><em>Step(ii):-</em></u>
Slope - intercept form
5 y = 3x -26
