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
I am pretty sure it is 120 or 30
Answer:
The height of the model is 138 cm.
Step-by-step explanation:
Simply multiply the height by the scale factor.
230*0.006
= 1.38 m
We need to convert this measure to centimeters. Centimeters are 1/100 of a meter. Therefore, we can multiply 1.38 meters by 100 to find how many centimeters it is equal to.
1.38*100 = 138
The height of the model is 138 cm.
