20 is the answer your looking for
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:)

Answer:
Q7) 25.5
Q8) 25
Q9) 10
Q10) 12.7
Q11) 34
Q12) 24
Step-by-step explanation:
Q7) c² = a² + b²
x² = 18² + 18²
x = √18² + 18²
x = 18√2 = 25.5
Q8) c² = a² + b²
x² = 20² + 15²
x = √20² + 15²
x = 25
Q9) c² = a² + b²
26² = 24² + x²
x = √26²-24²
x = 10
Q10) c² = a² + b²
x² = 9² + 9²
x = √9² - 9²
x = 9√2 = 12.7
Q11) c² = a² + b²
x² = 30² + 16²
x = √30² + 16²
x = 34
Q12) c² = a² + b²
25² = x² + 7²
x = √25² - 7²
x = 24
