Answer:
1072.33 cm^3
Step-by-step explanation:
formula
(2/3)*pi*(r)^3
Sue rounded both numbers to the nearest whole number.
1.25 to 1, since 1.25 is closer to 1 than it is to 2.
-2.69 round to -3, since it is closer to -3 than it is to -2.
Answer:
C. The ratio of the area to the circumference is equal to half the radius.
Step-by-step explanation:
The area of a circle can be written as;
Area A = πr^2
The circumference of a circle is;
Circumference C = 2πr
Using the formula, w can derive the relationship between the two variables.
A = kC
k = A/C
Substituting the two formulas;
k = (πr^2)/(2πr) = r/2
So,
A = (r/2)C
A/C = r/2
The ratio of the area to the circumference is equal to half the radius.
Given;
Area = 200.96
Circumference = 50.24
Radius = 8
To confirm;
k = r/2 = 8/2 = 4
Also,
A/C = 200.96/50.24
A/C = 4
Answer:
350 people can fit into 42 rooms
Step-by-step explanation:
So we can write it as a relation fraction equation:
Where:
x represents the people can fit in 42 rooms
Therefore, <u>350 people can fit into 42 rooms.</u>
I hope it helps you!
