A leather ball has a diameter of 28.4 cm. Which is the area of the piece of leather used on the surface of the ball?
Ira Lisetskai [31]

Answer:

A=806.56\pi\ cm^2

Step-by-step explanation:

Given that,

The diameter of a leather ball, d = 28.4 cm

Radius, r = 14.2 cm

We need to find the area of the piece of leather used on the surface of the ball. The surface area of the ball is given by :

A=4\pi r^2\\\\A=4\times \pi\times (14.2)^2\\\\A=806.56\pi\ cm^2

So, the area of the piece of leather is 806.56\pi\ cm^2. The correct option is (b).

An ice cream cone has height of 6 inches and a diameter of 2 inches what is the volume in cubic inches of the ice cream
GrogVix [38]

keeping in mind that radius is half the diameter, we know this cone has a diameter of 2 inches, so it has a radius of 1 inch, kinda small really for ice-cream, but anyhow.

\textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=1\\ h=6 \end{cases}\implies V=\cfrac{\pi (1)^26}{3}\implies V=2\pi \implies \underset{\textit{rounded up}}{V\approx 6}
