I need to find the surface area. it's a cut sphere with a diameter of 14.

alex41 [277]

Given data:

The diameter of the cut sphere, D=14 in.

The radius of the cut sphere is,

$\begin{gathered} r=\frac{D}{2} \\ r=\frac{14}{2} \\ r=7\text{ in} \end{gathered}$

The cut sphere is called a hemisphere.

The surface area of a sphere is

$A_1=4\pi r^2$

So, the lateral surface area of a hemisphere is half the surface area of sphere. Therefore, the lateral surface area of a hemisphere is,

$\begin{gathered} A_2=\frac{4\pi r^2}{2} \\ A_2=2\pi r^2 \end{gathered}$

The hemisphere has a lateral surface and a circular surface. The area of the circular surface is,

$A_3=\pi r^2$

Therefore, the total area of the hemisphere is,

$\begin{gathered} A=A_2+A_3 \\ A=2\text{ }\pi r^2+\pi r^2 \\ A=3\text{ }\pi r^2 \end{gathered}$

The total surface area of a hemisphere is,

$\begin{gathered} A_{}=3\text{ }\pi r^2 \\ A=3\text{ }\pi\times7^2 \\ A=461.8in^2 \end{gathered}$

Therefore, the total surface area of the cut sphere is 461.8 square inches.

Find the product of 2/2 and 4/18 in simplest form. Also, determine whether the

Alisiya [41]

The product of the given two fractions are rational.

The given fractions include;

2/2 and 4/18

The product of the given fractions is calculated as follows;

$\frac{2}{2} \times \frac{4}{18} = \frac{2}{9}$

A rational number is a number that can be expressed in ratio form. These numbers are two integers expressed in form of fractions called numerator and denominators.

Irrational numbers cannot be expressed in form of simple ratios.

Thus, we can conclude that the product of the given two fractions are rational.

A scale drawing of a bathroom is shown below:

aleksandrvk [35]

Length of the actual bathroom = 20 x 2 inches = 40 inches = 10/3 ft
Width of the actual bathroom = 20 x 3.5 inches = 70 inches = 35/6 ft
Area of the actual bathroom = length x width = 10/3 x 35/6 = 19 square ft.
