<span>There are 4 pair of numbers that add up to 16. So you would need to choose at least 5 numbers to ensure that you got at least one of those pairs.</span>
No it can't really because a chord stretches across the whole circle (if you look up a chord online you'll see) and the radius is only half of the circle. Hope this helped:)
Using technology,
normalcdf(lower = 59, upper = 65, mean = 60, sd = 5)
= 0.4206 or 42.06%
Answer:
<h3>Area =Pi r2</h3>
=3.14×10x10
=3.14×100cm2
=3.14cm2
<h3>Perimeter = 2 pi r</h3>
=2 ×3.14×10
=6.28cm
Or =Pi d
= 3.14 ×20cm
=62.8cm
<h3>Note:</h3>
R means radius
D means diameter
radius is half of a diameter e.g radius is10 and diameter is 20
I can recommend you watching yt videos it helped me alot
hoo this helps:)
