Describe the relationship between the area of a circle and its circumstances

valentina_108 [34]

Answer:

$A = \frac{r}{2}C$

Step-by-step explanation:

Given

Shape: Circle

Required

The area and the circumference (relationship)

This implies that, we write an expression that relates the area and the circumference.

Circumference is calculated as:

$C = 2\pi r$

Area is calculated as:

$A = \pi r^2$

The area can be rewritten as:

$A = \frac{2\pi r^2}{2}$

Further rewrite as:

$A = \frac{r}{2}*2\pi r$

Recall that: $C = 2\pi r$

So, the expression becomes

$A = \frac{r}{2}*C$

$A = \frac{r}{2}C$

Expand<br> c(3c - 3)<br> I need help on this

Rudik [331]

$\\ \sf\longmapsto c(3c-3)$

Apply distributive law

a(b-d)=ab-ad

$\\ \sf\longmapsto 3c(c)-3(c)$

$\\ \sf\longmapsto 3c^2-3c$

We can still take common

$\\ \sf\longmapsto 3c(c-1)$

Write the equation 2x - 3y = 6 in slope-intercept form.

ExtremeBDS [4]

Answer:

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

Step-by-step explanation:

$2x - 3y = 6 \\ - 3y = - 2x + 6 \\ \\ y = \frac{ - 2}{ - 3} x + \frac{6}{ - 3} \\ \\ \huge \purple{ \boxed{ y = \frac{ 2}{ 3} x - 2}} \\ this \: is \: in \: the \: slope - intercept \: form.$
