Hey! For these questions I'd reccomend m4thm4y. Ps I replaced the a with 4.
Answer: 4 or 
To find the square root of a number, remember that there will be two factors that are the same that will give you the product.
Lets start from 1:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.
4 and 4 are the same numbers.
Therefore, 
= 4
It can also be written as
Answer:
The correct option is C. 47.10 inches
Step-by-step explanation:
Diameter of the tire rim is given to be 15 inches
So, The radius of the tire rim will be 7.5 inches
Now, we need to find the circumference of the tire rim
And, The circumference of the tire rim is given by the formula :
Circumference = 2·π × radius
⇒ Circumference of the tire rim = 2 × 3.14 × 7.5
⇒ Circumference of the tire rim = 47.1 inches
Therefore, The correct option is C. 47.10 inches
Answer:
Step-by-step explanation:
False,true,true
All circles are similar.
If they were congruent, they would have the same radius's/diameter's.
Circle B = diameter of 6
Circle A = radius of 4
Diameter = 2 * Radius
Circle A = diameter of 4 * 2 = 8
So they have different diameter's, therefore they are not congruent. So they are similar only.
