Hello there.
Answer: Work out the volume of both:
20 x 15 x 10 = 3000
3 x 3 x 3 = 27.
Subtract the inside part:
3000 - 27 = 2973.
Hope This Helps You!
Good Luck Studying ^-^
Answer:
Benjamin travels 7 meters in 100 seconds.
Step-by-step explanation:
We are given the following in the question:
Circumference of tire = 2.8 m
Revolution of time = 1.5 times per minute.
Total time = 100 seconds.
We have to calculate distance covered by Benjamin.
Total number of revolution of tires =

Total distance covered by Benjamin =

Thus, Benjamin travels 7 meters in 100 seconds.
The square root of 78 is an irrational number, so the exact number
can't be written down, no matter how long you make the decimal.
If I say it's 8.8318, then my answer is too big, but only by about 0.0004 percent.
Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)
Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
