Well, 18 yards is 54 feet.
Answer:
r = 51.96 inches
Step-by-step explanation:
![V_{cone} = \pi {r}^{2} h \\ \\ \implies \: r^{2} = \frac{V_{cone}}{\pi h } \\ \\ \implies \: r^{2} = \frac{942}{3.14 {(9) } }\\ \\ \implies \: r^{2} = \frac{942}{3.14 {(9) } } \\ \\ \implies \: r^{2} =2700 \\ \\ \implies \: r= \sqrt{2700} \\ \\ \implies \: r=51.96 \: inches](https://tex.z-dn.net/?f=V_%7Bcone%7D%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h%20%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20r%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7BV_%7Bcone%7D%7D%7B%5Cpi%20h%20%7D%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20r%5E%7B2%7D%20%3D%20%20%5Cfrac%7B942%7D%7B3.14%20%7B%289%29%20%7D%20%7D%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20r%5E%7B2%7D%20%3D%20%20%5Cfrac%7B942%7D%7B3.14%20%7B%289%29%20%7D%20%7D%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20r%5E%7B2%7D%20%3D2700%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20r%3D%20%5Csqrt%7B2700%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20r%3D51.96%20%5C%3A%20inches)
Answer:
The bus will travel 20km within 15 minutes
Step-by-step explanation:
If Erica earned a total of $15450 last year from both the jobs then he earns $2840 from college if she earned 1250 more than four times the amount from college from store.
Given Total amount earned=$15450,Amount earned from store is 1250 more than 4 times earned from college.
Amount from store forms an equation.
let the amount earned from college is x.
According to question:
Amount earned from store=4x+1250
Amount earned from college=x
Total amount earned=4x+1250+x
5x+1250=15450
5x=15450-1250
5x=14200
x=14200/5
x=2840
Put the value of x in 4x+1250 to get amount earned from store=4(2840)+1250=$12610.
Hence the amount earned by Erica from college is $2840.
