The square root of 25 is 5.
Your just trying to find what number you can multiply with its self to make that number. So 5x5 = 25
Another example is lets say 64, the square root of 64 is 8 because 8x8 = 64.
Hope this makes sense!!
Hope this Helps!!

In order to solve this inequality, we should divide both sides by 9:-

Why 9? Because x is multiplied by 9, and we need to isolate x in order to find its value.

Hence, that's the solution to the inequality.
<em>It also means that the numbers less than 8 will satisfy the given inequality (make the inequality true)</em>
(Option C is correct :) )

The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 .

: Plug in the value we just found for r.
3.

: Use the order of operations (PEMDAS).
4.

The area of the circle is equal to
Dunno the question... But I sure hope if you jump out of a plane the parachute is ALREADY inspected :d
