First you need to find the radius. To do that you need to divide the diameter by two;

45 / 2 = 22.5

Then you plug the radius in the formula for a sphere. Which is...

V = (4 / 3)πr^3
First you need to find the volume with out pi

V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3

Answer:

47732.14 cm³

Step-by-step explanation:

To find the volume of the sphere with a diameter of 45 cm, we simply use the formula for calculating volume of a sphere, since a base ball is also spherical in shape.

Volume of a sphere = 4/3 πr³

But in the question, we were given diameter, so we can find our radius using the diameter given.

radius = diameter / 2

radius = 45 / 2

radius(r) =22.5 cm

The constant value of π is always 22/7 or 3.142 unless stated otherwise.

We can now go ahead and insert our values into the formula;

Volume of baseball = 4/3 πr³

                                  =4/3 × 22/7  × (22.5)³

                                  = 1002375   /    21

                                  =47,732.14 cm³

Volume of the baseball = 47,732.14 cm³

Hello!

\large\boxed{\text{ slope = -3}}

Use the slope formula to solve for the slope of the line (m):

m = \frac{y^{2} -y^{1} }{x^{2} -x^{1} }

We can plug in the points (0, 4) and (1, 1) to solve:

m = \frac{1-4}{1-0}= \frac{-3}{1}  = -3

Therefore, the slope of the line is -3.

Express the given logarithm in terms of common logarithms. Then approximate its value to four decimal places.
zhannawk [14.2K]

Answer:

3.4594

Step-by-step explanation:

To change the base of a logarithm

• log_{b} x = \frac{log_{c}x }{log_{c}b }

where c represents the new base

Changing the base from 2 to 10

log_{2} 11 = \frac{log_{10}11 }{log_{10}2 } ≈ 3.4594
