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:
it would be a distance of 7 units
Step-by-step explanation:
Answer:
(f + g)(x) = – 3x^2 + 5x - 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= 5x^2 + 9x – 4 + (– 8x^2 – 3x – 4)
= 5x^2 + 9x – 4 – 8x^2 – 3x – 4
Combine
= – 3x^2 + 5x - 8
Answer:
The number 32 is part of the solution set
The circle on the graph is closed
The arrow on the graph points to the left
Step-by-step explanation:
The number 32 is part of the solution because it said that water freezes at 32 degrees when it is at or below 32
The circle on the graph is closed because 32 is part of the answer , when the solution is showed then the circle is closed.
Last but not least the arrow on the graph points left because water freezes when it is at 32 or below 32 degrees, so when it points left the numbers become lower.
Hope this helped! :)
