The diameter of a softball is 3.8 inches. Estimate the volume within the softball. Round answers to the nearest whole number and

bekas [8.4K]

Answer:

Volume of softball is 29 cubic inches.

Step-by-step explanation:

Here we are given that the diameter of a softball is 3.8 inches.

To find the volume of the softball, we must consider the volume of a sphere formula, which is given by:

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

We also know that radius is half of diameter.

Radius of softball is half of 3.8 which is 1.9 inches.

Plugging this value in the formula, we have

$V=\frac{4}{3}\pi (1.9)^{3}$

Volume = 28.73 cubic inches.

Rounding to the nearest whole number:

Volume of softball will be 29 cubic inches.

What is the difference?

Whitepunk [10]

Answer:

$\frac{x^2+3x -12}{(x-5) (x +3)(x+7)}$

Step-by-step explanation:

Given

$\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}$

Required

Calculate the difference

We start by factorizing the denominator of both fractions

$\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}$

$\frac{x}{x^2+3x - 5x -15} - \frac{4}{x^2+7x - 5x-35}$

$\frac{x}{x(x+3) - 5(x +3)} - \frac{4}{x(x+7) - 5(x+7)}$

$\frac{x}{(x-5) (x +3)} - \frac{4}{(x-5)(x+7)}$

Take LCM

$\frac{x(x+7) - 4(x +3)}{(x-5) (x +3)(x+7)}$

Open Brackets

$\frac{x^2+7x - 4x -12}{(x-5) (x +3)(x+7)}$

$\frac{x^2+3x -12}{(x-5) (x +3)(x+7)}$

This can't be simplified any further;

liraira [26]

Answer:

6b < 24

⇔ b < 24/6

⇔ b < 4

4b + 12 > 4

⇔ 4b > 4 - 12

⇔ 4b > -8

⇔ b > -8/4

⇔ b > -2
