Force = mass x acceleration
Force = 70 kg x 2 m/s^2
Force = 140 N
Step-by-step explanation:
the volume of a cylinder is
base area × height.
and the base is a circle, and the area of a circle is
pi×r²
remember, the radius is half the diameter.
so, in our case, the volume is
pi×(18/2)²×20 = pi×9²×20 = pi×81×20 = pi×1620 =
= 5,089.380099... in³ ≈ 5,089 in³
<span>0.36 with a line over the 36 means a repeating decimal
0.36363636363636 etc
= 36/99 = 4/11</span>
I'm going to assume that you accidentally missed a set of parentheses and that the expression is

Raise 2,

, and

to the third power:

When a variable raised to a power is raised to another power, the exponents are multiplied:

Negative powers are the positive power in the denominator:

Therefore, the answer is the second option.
First find the side EC by setting up ratio. use pythagorean theorem to find the hypotenuse side.
