Answer:
Step-by-step explanation:
Use the formula of distance between the two points and ,
Distance =
1. Distance between A(3, 4) and B(8, 12),
AB =
AB =
=
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD =
=
=
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY =
=
=
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM =
=
=
= 10.77
Answer:
The area of circle is 706.95 cm²
Step-by-step explanation:
For a given Circle,
Diameter (d) = 30 cm
Radius (r) = ³⁰/₂ = 15 cm
π = 3.142
Now,
Area of Circle
<h3>
<u>Formula</u><u>:</u></h3>
<u>A</u><u> </u><u>=</u><u> </u><u>πr</u><u>²</u>
A = 3.142 × (15)²
A = 3.142 × 15 × 15
A = 706.95 cm²
Thus, The area of circle is 706.95 cm²

Like... 276 divided by 4... My 4th grade teacher is teaching us a way of long division, here are the steps. Divide, Multiply, Subtract Bring down, Repeat... Here is the example. 4 to 2, I cant make 2 with 4. 4 is too big, then i go to 27. the closest i can get is 6x4 to make 24. then on top i put 6, then i multiply 4x6 and put 24 down below 27. Then I subtract then bring down the 6. Next step, repeat. Do 4 divided by 3, the closest i can get to 4 is by doing 3x1 so i put the 1 up by the 6 then multiply 1x4. Which is 4, then i bring it down then subtract 36 - 4. You get 61 with a remainder of 4. :) Hope that helped and isn't too confusing!
