16 in^2 is the surface area so 16^2 divided by 2x pi which is 3.142 I think - 2x1.5 to find h.Sorry I rushed I’ll write correctly later

B) The hypotenuse is 15 inches.

Step-by-step explanation:
If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete
![\dfrac{1}{6}+\dfrac{1}{7}=\dfrac{7+6}{42}=\dfrac{13}{42}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B6%7D%2B%5Cdfrac%7B1%7D%7B7%7D%3D%5Cdfrac%7B7%2B6%7D%7B42%7D%3D%5Cdfrac%7B13%7D%7B42%7D)
of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is
![\dfrac{42}{13}\cdot 60 \approx 194](https://tex.z-dn.net/?f=%5Cdfrac%7B42%7D%7B13%7D%5Ccdot%2060%20%5Capprox%20194)
So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
Y = 4x - 7 is a line with a slope of 4 and y-intercept of -7.
plug in any X value, for example 1 and you get the following
y = 4(1) - 7
y = -3
(1,-3) is a point that satisfies the equation y = 4x - 7
