Answer:
V = 0.52 cm³
Step-by-step explanation:
radius r = 0.5 cm
volume V = 0.523333333 cm³
surface area A = 3.14 cm²
circumference C = 3.14 cm
In Terms of Pi π
volume V = 0.166666667 π cm³
surface area A = 1 π cm2
circumference C = 1 π cm
Agenda: r = radius
V = volume
A = surface area
C = circumference
π = pi = 3.1415926535898

Volume of a sphere:
V = (4/3)πr³
Circumference of a sphere:
C = 2πr
Surface area of a sphere:
A = 4πr²

Answer:
1: 
2: 
3: 
Step-by-step explanation:
Question 1: When lines are parallel, that means they're slope is the same and there y-intercept is different. So the first step is to calculate the slope of BC. If you look at BC you'll notice it goes down by 2 and goes forward by 2 so the slope is -2/2 or -1. This completes one part of the slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept will be calculated using the point A. since the equation passes through point A
-1 = (-2)(-1) + b
-1 = 2 + b
-3 = b
y=-1x-3
Question 2: Same concept here, if you look at AC, you'll see it "rises" by 4 and "runs" by 5, thus the slope is 4/5. Since it passes through B we'll use that to find the y-intercept
5 = (4/5)(1) + b
5 = 4/5 + b
b = 4.2
Question 3: It "rises" by 6 and "runs" by 3, thus the slope is 6/3 which is 2.
Plug in known values
3=(3)(2) + b
3 = 6 + b
-3 = b
