Answer:

A = pi*(8 mm)^2 = 64*pi mm^2

Step-by-step explanation:

The formula for the area of a circle is A = pi*r^2, where r is the radius. Thus, r^2 = (25pi) / pi, or 25, and r = 5 mm.

If we increase this radius by 3 mm, we get the new radius 8 mm. The area of the new circle will thus be A = pi*r^2, or, in this particular case,

A = pi*(8 mm)^2 = 64*pi mm^2.

Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log( $\frac{I}{S}$ )

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now M1=log( $\frac{I1}{S}$ )------1

M2=log( $\frac{I2}{S}$ )-----2

Now subtract 1 and 2 we get

M1-M2=log( $\frac{I1}{I2}$ )

I1/I2= $10^{M1-M2}$

I1=I2( $10^{0.8}$

I1=I2*6.31

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Let h bet the # of hours worked

If Cynthia earns $13 per hour then her equation would be:

C = $13h

If Amy makes $1.5 more per hour then her equation would be:

A = $14.5x

Now lets plug in some numbers:)

A = $14.5(43.5)

A = $630.75
