How do you round the area of a circle with 3.14?

kirill115 [55]

Answer:

(This is a example since you don’t have anything to round to)

Example Answer if the radius is 4 - 50.24

Step-by-step explanation:

Example Radius : 4

Area : 3.14

We have the mulitiply 3.14 times The Example Radius 2 times because The diameter of a circle is 2 times its radius.

( 3.14 x 4 x 4) 50.24

If you know the diameter, it’s a half or 1/2 as large.

Therefore, if the radius was 4, it would be 50.24.

Youre welcome :)

CB = 4, CA = 11 , and CE = 8 , what is the length of overline ET ?

erma4kov [3.2K]

AB=11-4=7

$\\ \rm\hookrightarrow \dfrac{BC}{AB}=\dfrac{CE}{ET}$

ET be x

$\\ \rm\hookrightarrow \dfrac{4}{7}=\dfrac{8}{x}$

$\\ \rm\hookrightarrow 4x=56$

$\\ \rm\hookrightarrow ET=x=14$

A ball of mass 0.4 kg flies through the air at low speed, so that air resistance is negligible. What is the net force acting on

arsen [322]

Answer:

-3.92 N

Step-by-step explanation:

We are given that

Mass of ball=0.4 kg

Acceleration due to gravity= $-9.8m/s^2$

Because the ball flies against to gravity

We have to find the net force acting on the ball while it is in motion.

We know that when there is no air resistance then the net force acts on the ball is equal to weight of ball.

Net force,F =mg

Substitute the values then we get

$F=0.4(-9.8)$

$F=-3.92N$

Hence, the net force acting on the ball while it is on motion=-3.92 N
