Surface Area of a Sphere = 4π(d/2)²
Let the smaller sphere's diameter be just a sample of 4 units in diameter and let the large spheres diameter be 4 times that of the smaller sphere.
Small Sphere: 4π(4/2)² = 16π units²
Large Sphere: 4π(16/2)² = 256π units²
256π / 16π = 16 times
The large sphere has a surface area 16 times that of the smaller one.
Answer:
y= 15
Step-by-step explanation:
Y= Kxz
y=6 x=1/2 z=6
15= K (1/2) (6)
15= K (3)
K= 5
SO
y= (5) (1/2) (6)
Y= 15
Answer:
The distance from Endnville to Concord = 14.8 miles
Step-by-step explanation:
∵ Westfalls is 7 miles South of Endnville
∵ Concord is 13 miles West of Westfalls
∵ South and West are ⊥
∴ The distance from Endnville to Concord = √(7)² + (13)²
= 14.8 miles
