What is the volume of a sphere with a diameter of 18 centimeters? use 3.14 for pi.

3052.08

Step-by-step explanation:

The equation to find volume with diameter is:

V=⅙πd³

So you would take pi, the diameter, and cube it. You'd have something that looks like this:

π18³

Take both of these and put them over 6, and divide. Multiply by pi at the end to get your solution.

I hope this helped!

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
