Answer:
20.25 m²
Step-by-step explanation:
the area (A) and circumference (C) of a circle are calculated using the formulae
C = 2πr and A = πr² ( where r is the radius )
calculate the radius using the formula for circumference
2πr = 9π ( divide both sides by 2π )
r = 
= 
= 4.5, hence
A = π × 4.5² = 20.25π m²
Percent means per one hundred so we can say that:
p/100≈(28)/(28+81+45+63+35) guessing with my old eyes :)
p/100≈28/252
p≈2800/252
p≈11.11%
So rounded to the nearest 5% you'd have:
p≈10%
Answer:
1, 33.3
2, 81.9
3, 240
4, the farmer sold 33.3 of his crops
5, 750 students are enrolled.
If u use scientific notion the answer for the first one would be 10^8 the second one would be 10^11 and the last one would be 10^10
Hope that Helps >.< <span />
