Formula: A = πr²

Divide to find the radius.

6 / 2 = 3

Solve using the values we are given and solved for.

A = π(3)²

A = 9π

A ≈ 28.26

Best of Luck!

Answer:

28.26 miles

Step-by-step explanation:

Area= pi times radius squared

diameter is twice the radius so 6÷2=3miles

3 miles is the radius

So A= 3.14 × 3²

= 28.26

Answer:

=1.500

Step-by-step explanation:

(((7•(x-2))-3x)+5)-((0-2•(5x-4))+4) = 0

STEP

Equation at the end of step 2

((7 • (x - 2) - 3x) + 5) - (12 - 10x) = 0

STEP

Pulling out like terms

4.1 Pull out like factors :

14x - 21 = 7 • (2x - 3)

Equation at the end of step

7 • (2x - 3) = 0

STEP

Equations which are never true

5.1 Solve : 7 = 0

This equation has no solution.

A non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2 Solve : 2x-3 = 0

Add 3 to both sides of the equation :

2x = 3

Divide both sides of the equation by 2:

x = 3/2 = 1.500

One solution was found :

x = 3/2 = 1.500

The expression 32−48 factored using the GCF is .

Ulleksa [173]

Answer:

Step-by-step explanation:

The largest factor that will divide evenly into both 32 and 48 is 16.

Thus, 32 - 48 = 16(2 - 3), or 16 (-1), or just -16.

Answer :- 

the quotient is ( 4x² - 5x + 7 )

Step-by-step explanation:

[ Refer to the attachment for steps ]

We have to eliminate the highest degree coefficient in each step.

And as in division of normal numbers we subtract the things here we do the same ,

but while subtracting we have to take care about the signs !

The negative sign changes the negative sign into positive sign and positive sign into negative sign.

Whereas , a positive sign don't changes the sign.

Answer:

4.71 minutes

Step-by-step explanation:

Incomplete question [See comment for complete question]

Given

Shape: Cone

$r = 3$ -- radius

$h = 7$ --- height

$Rate = 14in^3/min$

Required

Time to pass out all liquid

First, calculate the volume of the cone.

This is calculated as:

$V = \frac{1}{3} \pi r^2h$

This gives:

$V = \frac{1}{3} * 3.14 * 3^2 * 7$

$V = \frac{1}{3} * 197.82$

$V = 65.94in^3$

To calculate the time, we make use of the following rate formula.

$Rate = \frac{Volume}{Time}$

Make Time the subject

$Time= \frac{Volume}{Rate }$

This gives:

$Time= \frac{65.94in^3}{14in^3/min}$

$Time= \frac{65.94in^3}{14in^3}min$

Cancel out the units

$Time= \frac{65.94}{14} min$

$Time= 4.71 min\\$
