An engineer is designing a cylinder-shaped structure using the formula shown below. As shown, an approximation of 22/7
for pie is used in the formula.
The engineer is considering using different values for r , the radius in meters, and h, the height in meters. Which pair of values makes V , the volume in cubic meters, an irrational number?
A.
r=3 and h=6.54
B.
r=√11 and h=6.54
C.
r=√11 and h=√9
D.
r=3 and h=√15
C. r=√11 and h=√9
In this case, both r=√11 and h=√9 are irrational numbers. When multiplied together to calculate the volume using the formula V=πr^2h, the result will be an irrational number.
