Answer:

1385mm squared

Step-by-step explanation:

Area of Circle formula: A = pi r^2

You need to divide 42mm by 2 since that is a diameter.

*Half of the diameter is the radius*

42/2 = 21

Now, do 3.14 multiplied by 21 to the power of 2.

Formula: A = 3.14 x 21^2

Do 21^2 first.

That shall be 441

Now do 3.14 x 441

1,384.74mm - That is your exact answer.

The directions tell you to round it to the nearest whole number

THAT IS 1385mm squared

Solve for x: |x − 2| + 10 = 12
raketka [301]
✯<span>Let's solve this equation step-by-step!
</span>✯<span>is the question you've asked us today:
|x − 2| + 10 = 12

</span>✯<span>Add -10 to both sides:
</span><span><span><span>|x−2|</span>+10</span>+−10</span>=<span>12+<span>−10
</span></span>
✯<span>Solve Absolute Value:
</span><span>|x−2|</span>=<span>2
</span>
✯We know either: 
<span>x−2=2 </span>or <span>x−2=<span>−<span>2
</span></span></span>
(Possibility 1) <span>x−2=2
</span>
(Add 2 to both sides) <span><span>x−2+2</span>=<span>2+2
</span></span>
x=<span>4
</span>
(Possibility 2) <span>x−2=<span>−2
</span></span>
(Add 2 to both sides) <span><span>x−2+2</span>=<span>−2+2</span></span>

x=<span>0
</span>
✯So since we have gotten x=4 and x=0 you answer shall be:

B. x=4 and x=0

✯I hope this helps!<span>✯</span>

Step-by-step explanation:

Given

Momentum of boy P=200\ kg.m/s

Mass of boy is m=20\ kg

Momentum is the product of mass and velocity

P=mv

Substitute value

\Rightarrow 200=20\times v\\\Rightarrow v=10\ m/s

Thus, the boy is moving with a velocity of 10 m/s
