The formula for a circumference is L=pi*diameter
So you have to replace d for 500:
L=circumference= 3.14*500 = 1570 kilometers, so answer is "b"
Answer:
400 cm²
Step-by-step explanation:
(side2/side1)³ = Volume2/Volume
2³ = 64000/X
X = 64000/8
X = 8000
Volume = side³
8000 = side³
Each side = 20
Area of a face = side²
= 20² = 400 cm²
Answer:
Y=3
Step-by-step explanation:
-1= 1/2
1/2=-1
x=-1
y=3
Hope this helps!
