A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)

Hatshy [7]

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

Can someone tell me if my answer to this problem is correct, please? And if it isn't how do you solve it?

Mrac [35]

Answer:

Height of tree= 13.8m

Step-by-step explanation:

When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.

Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)

I have attached my working too.
