Replace x^2+y^2 with r^2. Also replace y with r*sin theta.
Then we have r^2 = r*sin theta.
this can be reduced to r = sin theta.
Answer:
11 mm
Step-by-step explanation:
Put the given numbers in the given formula and solve for the radius.
V = 1/3πr²h
968π = 1/3π·r²·24
121 = r² . . . . . . . . . . . divide by 8π
r = √121 = 11 . . . . . . take the square root
The radius of the piece is 11 mm.
Answer:
24.075, 24.008, 21.605, 21.048
Answer:
x < -3 or x ≥ 5
Therefore the correct option is the first one.
Step-by-step explanation:
1. all real numbers that are less than –3 or greater than or equal to 5
the above can be written as
x < -3 or x ≥ 5
Therefore the correct option is the first one.
Round to the neatest cubic centimeter. The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .
