Question

Find the area of the circle 5 ft rounded to the nearest tenth

Answer 1

Answer:

This one, in my opinion, is very simple. Though it may not be easy for some people that are just now learning about this stuff, they can always learn with brainly! The answer is 78.5$ft^{2}$

Step-by-step explanation:

So first, you need to know the correct formula in order to find the area of a circle, which is $\pi r^{2}$, or pi times radius squared. Since we know that pi is equal to about 3.14, and the radius is 5, then do the following: multiply 5 by 5. You should get 25. (you'll need a calculator for the next part if you are wanting to solve it along with this explanation. Now, since you have solved some of the equation, you can update it. It should look like this: $\pi \times 25$, or pi times 25. Since we have already analyzed that pi is equal to about 3.14, then all you need to do is 25 times 3.14, or if your calculator has it, 25 times $\pi$. It should equal 78.5 if you did 25 times 3.14, but if you entered "$25 \times \pi$", then your calculator should solve it to have an answer of 78.5398163397, which if you round to the nearest hundredth, it should equal 78.54. But if you need the rounded tenth, don't worry! This number rounded to the nearest tenth is 78.5$ft^2$. I really hope this helps you! If I made a mistake or if it is wrong, then please comment on this question and let me know. Have a great day!
