The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

C=2\pi r

putting the values

75.36 = 2*3.14*r\\75.36 = 6.28r

Dividing both sides by 6.28

\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm

The area of circle is given by:

A = \pi r^2

Putting the values

A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2

Hence,

The area of flying disk is 452.16 square centimeters

Answer:

a=22.5\ units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

so

In this problem

If polygon RSUPE is similar to polygon KQUIC

then

\frac{RS}{KQ}=\frac{RE}{KC}

substitutes the values and solve for a

\frac{a+2}{14}=\frac{17.5}{10}\\ \\10a+20=14*17.5\\ \\10a=245-20\\ \\a=225/10\\ \\a=22.5\ units
