Answer:

Step-by-step explanation:

The formula to find the circumference of a circle is :

C = 2 π r

Given that, the circumference of the circle is 149 mm.

First, let us find the radius of the circle.

C = 2 π r

149 = 2 × 3.14 × r

149 = 6.28r

Divide both sides by 6.28.

23.72 = radius

Now let us find the area of the circle.

The formula to find the area of the circle.

A = π r²

Let us find it now.

A = 3.14 × 23.72²

A = 3.14 × 562.6384

A = 1766.7mm²

-3(-6b+5)? Solve bih

madam [21]

Answer:

$18b - 15$

Step-by-step explanation:

Step 1: Distribute

$-3(-6b + 5)$

$(-3 * -6b) + (-3 * 5)$

$18b - 15$

Answer: $18b - 15$

If needed solve for b

$18b - 15 + 15 = 0 + 15$

$18b / 18 = 15 / 18$

$b = 0.8333...$

Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the eq

lawyer [7]

Answer:

The value of rate of decrease of volume = - 3600 $\frac{k pa}{min}$

Step-by-step explanation:

According to Boyle's law P V = C ------- (1)

Pressure ( P ) = 100 k pa = 10 $\frac{N}{cm^{2} }$

Volume ( V ) = 900 $cm^{3}$

Put these values in equation ( 1 ) we get,

⇒ C = 10 × 900 = 9000 N-cm = 90 N-m

Differentiate Equation ( 1 ) with respect to time we get,

⇒ V $\frac{dP}{dt}$ + P $\frac{dV}{dt}$ = 0

⇒ V $\frac{dP}{dt}$ = - P $\frac{dV}{dt}$

⇒ $\frac{dV}{dt}$ = - $\frac{V}{P}$ $\frac{dP}{dt}$ ---------- (2)

This equation gives the rate of decrease of volume.

Given that Rate of increase of pressure = $\frac{dP}{dt}$ = 40 $\frac{k pa}{min}$

C = 90 N-m

P = $10^{5}$ pa = 10 $\frac{N}{cm^{2} }$

V = 900 $cm^{3}$

Put all the above values in equation 2 we get,

⇒ $\frac{dV}{dt}$ = - $\frac{900}{10}$ × 40

⇒ $\frac{dV}{dt}$ = - 3600 $\frac{k pa}{min}$

This is the value of rate of decrease of volume.
