Answer:

area of this circle: 490.6 inch²

Step-by-step explanation:

area of circle: π(radius)²

Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in

using the formula:

3.14(12.5)²

490.625 inch²

490.6 inch²____rounded to nearest tenth.

<h3>Given:</h3>

$\\$

Diameter of circle = 25in.

$\\$

$\\$

Area of circle.

$\\$

<h3>Explanation:</h3>

$\\$

So as Diameter is given , let's covert it into radius.

We know:

$\\$

$\bigstar \boxed{ \rm Diameter \: of \: circle \: = 2 \times radius}$

$\\ \\$

$\hookrightarrow \sf Diameter \: of \: circle \: = 2 \times radius \\$

$\\ \\$

$\hookrightarrow \sf 25 = 2 \times radius \\$

$\\ \\$

$\hookrightarrow \sf radius \: = \dfrac{25}{2}$

$\\ \\$

$\hookrightarrow \bf radius \: = 12.5 in.$

Now Let's find circumference of circle:

we know:-

$\\ \\$

$\bigstar \boxed{ \rm Circumference \: of \: circle \: = \pi radius^2}$

$\\$

So:-

$\\ \\$

$\dashrightarrow \sf Circumference \: of \: circle \: = \pi radius^2\\$

$\\ \\$

$\dashrightarrow \sf Circumference \: of \: circle \: = 3.14\times (12.5)^2\\$

$\\ \\$

$\dashrightarrow \sf Circumference \: of \: circle \: = 3.14 \times 156.25\\$

$\\ \\$

$\dashrightarrow \bf Circumference \: of \: circle \: = 490.63\\$

$\\ \\$

$\bf\dag \underline {\blue{\frak{ Circumference \: of \: circle \: = 490.63 in(approx)}}}$

What is 3x-4y=4 in linear equations

KengaRu [80]

Your equation is a linear equation because it has a constant, and it has variables. And it does not have something like x^2.

However, if your question wants it in slope-intercept format, which is y=mx+b

Then:

3x-4y = 4

We can add 4y to both sides
3x = 4+4y

Subtract 4 from both sides
3x-4 = 4y

Then we divide by 4
$\frac{3}{4} x -1=y$

So 3x-4y=4 in slope-intercept format would be $y =\frac{3}{4} x -1$
