Answer:
V =192 pi or approximately 602.88 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
We need to determine the radius
r = d/2 = 8/2 =4
V = pi (4)^2 *12
V = pi *16*12
V =192 pi
We can approximate pi by 3.14
V = 192* 3.14
V =602.88 cm^3
Hello:<span>
the equation is : y = ax+b
the slope is a : a×(1/2) = -1......( perpendicular to a line with a slope of 1/2) because : -2x+4y =8...y=(1/2)x+2 ) </span>
<span>
a = -2 y=(-2x+b
the line that passes through (2,1) :1 = -2(2)+b
b =5
<span> the equation is : y = -2x+5</span></span>
Answer:
The slope=1
Step-by-step explanation:
(0,7)=(x,y) and (-4,3)=(`x,`y)
The formula for finding slope= `y - y/`x - x
3-7/-4-0
-4/-4
1
Therefore, the slope=1
6.5^2 x 6.5^2= 1785.0625
Answer: 1785.1 sq units
