Answer:
The graph represents a linear function that passes through the origin.
Step-by-step explanation:
Proportional functions can be represented by , where
is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.
Answer:
<em>Area = 254.34 inches ³</em>
Step-by-step explanation:
The formula to find the surface area of a sphere is:
To find the volume of the sphere, we first need to figure out the radius () of the sphere. We can accomplish this by reversing the formula that was used to find the surface area.
Divide both sides by pi ().
Divide both sides by 4.
Find the square root of both sides.
<em>radius = 9</em>
<em />
Insert the value of the radius into the formula for finding the volume of a sphere.
<em>Area = 254.34 inches ³</em>
