Practice problem
How would you find the area of this circle if you only know the circumference?
A = C24\text{A = }\dfrac{C^{2}}{4}A = 4C2
A = C24π2\text{A = }\dfrac{C^{2}}{4\pi^{2}}A = 4π2C2
A = C24π\text{A = }\dfrac{C^{2}}{4\pi}A = 4πC2
Not enough information.
Type a concept, like “slope” or “photosynthesis”.
