Answer:
a) r = √V/6π
b) r = 8 inches
Step-by-step explanation:
a) The volume V (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2 . Solve the formula for r .
Solving for r means making r the subject of the formula
= V=6πr²
Divide both side by 6π
V/6π = 6πr²/6π
r² = V/6π
r = √V/6π
b) Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.
r = √V/6π
V = 1206 ft³
r = √1206/6π
r = √(63.98028712294193)
r = 7.9987678503 inches
Approximately r = 8 inches
Answer:
The surface area is 10.26 feet.
Step-by-step explanation:
A=lw+l(w
2)2+h2+w(l
2)2+h2=0.8·0.8+0.8·(0.8
2)2+62+0.8·(0.8
2)2+62≈10.26131
Answer:
there's no graph??
Step-by-step explanation:
To find the area, we have to use the F.O.I.L. method to solve (3x-2)*(4x-7)
-> 12x^2-21x-8x+14
= 12x^2 - 29x + 14
So the area of the rectangle would be 12x^2 - 29x + 14.
