Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³
Volume of the cone = 1/3 π r² h
21π = 1/3 π (r)² (7)
r³ = 21π ÷ (7/3 π)
r² = 9
r = 3
Answer : Radius = 3
First find the square root of 900 to get one side of the square, which is 30 inches.
Formula for area of a circle: pi times the radius(squared)
The radius is 15 because one side of the square equals the diameter of the circle. 15 squared is 225.
3.14x225=<u>706.5 inches squared
</u>I hope this helps, because I did not have a diagram of the problem, but this should be the answer if the circle is inscribed in the square.<u>
</u>
It is a real number.
A real number is a combination of rational (usually negative) and irrational numbers.
A natural number is a positive integer.
But since -145 is a negative number it can't be a natural number. Making it a real number.
Correct me if I'm wrong.
1 = 7
2 = 10
