Answer:
9.5 feet
Step-by-step explanation:
So let's review the equations we need to know.
Circumference= π x d or π x 2r
Since we are solving for r, let's stick with the 2nd one.
Next, plug in the values.
59.66=3.14 x 2r
simplify.
59.66=6.28r
9.5=r
done!
the radius is 9.5 feet!
Answer:
4,5,6,7
Step-by-step explanation:
-1 < x ≤7 , x > 3 means that 3 < x ≤ 7
The solution of the equation –3x + 1 + 10x = x + 4 will be 1/2. Then the correct option is A.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The equation is given below.
–3x + 1 + 10x = x + 4
On changing, we have
6x = 3
x = 1/2
Then the correct option is A.

Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
