The radius of the inside circle is 8 inches. The radius of the larger circle is 4 inches more than the radius of the small circle.

What is the area in square inches of the shaded area? Use 3.14 for π and round your answer to the nearest whole number.

The Radius Of The Inside Circle Is 8 Inches. The Radius Of The Larger Circle Is 4 Inches More Than The

Answers

Answer 1

Answer:

Area of shaded region=2 ×3.14×R -2×3.14×r(where R is lager radius and r is smaller radius.)

Therefore area of shaded region=2×3.14×12 -2×3.14×8

=2×3.14(12-8)

=6.18 ×4

=24.72 inc^2

Justin is marking a border for a garden. He walks 200 feet to the east, then turns and

walks 120 feet due south, before finally walking in a straight line back to his original

starting point. To the nearest foot, how far does Justin walk in all?

Answer

feet

Answers

Answer:

d = 233.23 feet

Step-by-step explanation:

Given that,

Justin walks 200 feet to the east, then turns and  walks 120 feet due south.

We need to find the total distance walked by Justin. Let the distance be d.

We can use the Pythagoras theorem to find it such that,

[tex]d=\sqrt{d_1^2+d_2^2} \\\\d=\sqrt{200^2+120^2} \\\\d=233.24\ feet[/tex]

So, he walk 233.23 feet in all.

What is the sum of 4 3/10 + 3 6/10 =

Answers

Answer:

The sum is 10 times 11Step-by-step explanation:

Answer:

I just put it into my calculator, but if you don't have one here's how to solve this by hand.

First, figure out what 4 3/10 is. Once you figured that out, you should've gotten 43/10 = 4 3/10. Next do 3 6/10, you should get 18/5 = 3 6/10. This may seem like a useless part but it can help if you have a different learning method or thinking than others. How I found the 43/10 and 18/10 was that if you add the whole number and denominator and add the numerator then you get your sum fraction(s). 43/10 and 18/5.

Since both the original fractions above have a denominator of 10, the final sum will also have a denominator of 10. If you take your calculator and put in 43/10 + 18/5 and hit the = button, you should get 79/10 = 7 9/10.

Step-by-step explanation:

For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.

For 2, same thing, you have to find the gcf for the numbers and the variables.

3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".

4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.
