There are only one solutions
The area of a circle (A) is computed as follows:
![A=\pi\cdot\frac{D^2}{4}](https://tex.z-dn.net/?f=A%3D%5Cpi%5Ccdot%5Cfrac%7BD%5E2%7D%7B4%7D)
where D is the diameter of the circle.
From the picture, D = 81 ft. Using 22/7 as an approximation of π, we get:
Answer:
y-int = (0, -6)
Step-by-step explanation:
The y-intercept is the b-value of the equation of the line y = mx+b
To find the y-intercept plug in 0 for the x-value:
y=3(0) - 6
y= -6
-> x = 0, y = -6
Answer: 340 in. squared
Step-by-step explanation:
17*7=119
15*7=105
8*7=56
8/2*15=60
119+105+56+60=340 in.^2
