The answer should look like X<30 with a line under the less than sign, i hope this helps.
Answer:
You will pay $65.88 in total
Step-by-step explanation:
Bill amount: $54
Tip: 22% = $54 * 0.22 = $11.88
Sum up: $54 + $11.88 = $65.88
Formula: V = (2/3) π r 3.
Radius is 3cm.
So, now we can plug it in to solve for the volume.
V = (2/3) π 3^3
First, let's multiply 3^3.
3^3 = 27
Then, 27 x π = 84.82
After, multiply by 2/3.
84.82 x 2/3 = 56.55
Lastly, round 56.55 to the nearest tenth of a cubic centimeter.
56.55 = 56.6
Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.
