4 0

Answer:

Step-by-step explanation:

1. Write the equation

2. Multiply the 8 with what’s in the parenthesis so you would have 8r+32

3. Plus the opposite so you’d have +(-3)=85

4. Subtract 32 from 85 so your left with 53

5. Add -3 to 53 to get 56

6. You’ll be left with 8r=56

7. Divide 56 by 8

8. r=7

Calcular el volumen en m3 de la esfera en el que el área de uno de sus círculos maximos es 36pim2

Strike441 [17]

Answer:

The volume of the sphere is $V=288\pi\ m^3$

Step-by-step explanation:

The question in English is

Calculate the volume in m^3 of the sphere in which the area of one of its maximum circles is 36pi m^2

we know that

The radius of the maximum circle in the sphere is equal to the radius of the sphere

Step 1

Find the radius of the maximum circle

The area of the circle is

$A=\pi r^{2}$

we have

$A=36\pi\ m^2$

substitute and solve for r

$36\pi=\pi r^{2}$

Simplify

$36=r^{2}$

take the square root both sides

$r=6\ m$

Step 2

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

substitute the value of r

$V=\frac{4}{3}\pi (6)^{3}$

$V=288\pi\ m^3$

dedylja [7]

Answer:

Option C.300

Step-by-step explanation:

we know that

To find out how many times greater is the land area of the United States than that of Norway, divide the area of the United States by the area of the Norway

$\frac{9\times10^6}{3\times10^4}$

Remember that

To divide exponents (or powers) with the same base, subtract the exponents

$\frac{9\times10^6}{3\times10^4}=(\frac{9}{3})\times(10^{6-4} )=3\times10^2=300$
