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:)

<span> -1/2 - (-3/4)
= </span><span> -1/2 + 3/4
= - 2/4 + 3/4
= 1/4
hope it helps</span>
