As radius is a length so radius can't be negative.

But when measuring for speeds/simple harmonic motion etc radius can be negative, which means that it is measured on the perfectly opposite direction of a specified side of that circle. If radius is zero then it is not more a circle but it is a point.

Answer:

The lateral surface is 120 $in^2$ , which agrees with the third answer option of the list.

Step-by-step explanation:

Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.

Then the lateral area of the prism is:

Lateral area= 5 (6" x 4") = 5 (24) = 120 $in^2$

In a cinema, there are eight seats in a row. Four of the seats in one row are occupied. What fraction of seats are available in

Anarel [89]

Answer:

Step-by-step explanation:

Given,

There are 8 seats in a row.

There are 8 seats in a row.4 seats are occupied.

Available seats = 8 - 4 = 4 seats

Fraction of seats available:

$\frac{number \: of \: seats \: available}{total \: number \: of \: seats}$

$= \frac{4}{8}$

Reduce the fraction with GCF 4

$= \frac{1}{2}$

Hope this helps..
