What is the surface area of a sphere with a diameter of 12 centimeters ?

nasty-shy [4]

Answer:

$A=452.39\ cm^2$

Step-by-step explanation:

The formula to calculate the surface area of a sphere is the following:

$A=4\pi r^2$

Where A is the area of the sphere and r is the radius of the sphere.

In this case we know that the diameter d of the sphere is:

$d = 12\ cm$

The diameter is:

$d = 2r$ .

Thus

$r = \frac{d}{2}\\\\r = \frac{12}{2}\\\\r=6\ cm$

Then the surface area of the sphere is:

$A=4\pi (6)^2\\\\A = 144\pi\ cm^2\\\\A=452.39\ cm^2$

Forensic specialists can estimate the height of a deceased person from the lengths of the person's bones. These lengths are subs

Lera25 [3.4K]

Answer:

$130.2845\leq h\leq 137.7245$

Step-by-step explanation:

Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

$|h - (2.47f + 54.10)| \leq 3.72$

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

$|h - (2.47(32.25) + 54.10)| \leq 3.72\\|h - (79.9045 + 54.10)| \leq 3.72\\|h - (134.0045)| \leq 3.72\\$

If the modulus function is positive then:

$h - 134.0045 \leq 3.72\\h \leq 3.71+134.0045\\h\leq 137.7245$

If the modulus function is negative then:

$-(h - 134.0045) \leq 3.72\\-h+134.0045 \leq 3.72\\-h\leq 3.72-134.0045\\-h\leq -130.2845\\$

multiply through by -1

$-(-h)\geq -(-130.2845)\\h\geq 130.2845\\130.2845\leq h$

combining the resulting inequalities, the estimate of the possible range of heights will be $130.2845\leq h\leq 137.7245$
