Answer:
12.02 inches
Step-by-step explanation:
recall, volume of a cylinder is given by
V = πr²h
where r is the radius of the cylinder and h = the height
hence
9080 = π x r² x 20
r² = 9080 ÷ 20π = 144.513
r = √144.513 = 12.02 inches
Answer:
y=5/2x-8/3
Step-by-step explanation:
The equation is y=mx+b
M is the slope and b is the y-intercept.
Answer:
the answer is B -29 inches
Step-by-step explanation:
do the math they added 5 inches to 19 so just add 5 more inches
79.90*0.8= 63.92
Answer
63.92
Answer:
34 feet
Step-by-step explanation:
From the question, we are told that:
If the room is 30 feet high at the center and 90 feet wide at the floor,
Entire width of the room = 90 feet = 2a
a = 90/2 = 45
Height of the room = b = 30 feet
Foci (c)² = a² - b²
c = √a² - b²
c = √45² - 30²
c = √1125
c = 33.541019662 feet
Approximately to the nearest whole number = 34 feet
Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse
