Answer:
$2.95
Step-by-step explanation:
$22.95-$20
Problem 5
d = 29 = diameter
r = d/2 = 29/2 = 14.5 = radius
SA = surface area of sphere
SA = 4*pi*r^2
SA = 4*pi*(14.5)^2
SA = 841pi
SA = 841*3.14
SA = 2,640.74 square inches
To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.
2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft
<h3>Answer:
18.3 square feet (approximate)</h3>
=====================================
Problem 6
d = 10.7 = diameter
r = d/2 = 10.7/2 = 5.35 = radius
L = 22.3 = slant height
SA = surface area of the cone
SA = pi*r^2 + pi*r*L
SA = pi*(5.35)^2 + pi*5.35*22.3
SA = 147.9275pi
SA = 147.9275*3.14
SA = 464.49235
<h3>Answer:
464.49235 square cm (approximate)</h3>
Answer:
x < -6
Step-by-step explanation:
18 + x < 12
Subtract 18 from each side
18-18 + x < 12-18
x < -6
<span>This tells us two things. Our slope is 3 and our y intercept is -4.
This tells us that we need to start at (0,-4).
Plot that point.
Since our slope is 3 (3/1), move up 3 and right 1.
This you will end up at point (1,-1).
Connect these two points in a straight line, and you have graphed your line.
It will look like this</span>
