First use known volume to solve for radius:
![r=\sqrt[3]{\frac{3V}{4\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B4%5Cpi%7D%7D)
![r=\sqrt[3]{\frac{3(36\pi)}{4\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3%2836%5Cpi%29%7D%7B4%5Cpi%7D%7D)
![r=\sqrt[3]{27}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B27%7D)
Then use the radius to get the surface area:
Then use the radius to get the surface area:
193 meters in 2 seconds = meters in 1 minute

Answer:
(1.5,-2.6)
Step-by-step explanation:
Given the polar coordinates (-3,60°).
Let our Cartesian coordinates be (x,y)
#We know that when converting the rectangular coordinates (x,y) to polar (r,θ), then:
#Using the illustration above, we can express our polar coordinates as:
#Solve simultaneously to solve for x and y:
Hence, the Cartesian coordinates are (1.5,-2.6)
