Answer:
47.1: 50.24
Step-by-step explanation:
V= πr²(h/3)
= 3.14 x 3²(5/3)
= 3.14 x 9(5/3)
= 3.14 x 3(5)
= 3.14 x 15= 47.1
Volume of cylinder
V = πr²h
V = 3.14 x 2² x 4 = 3.14 x 4 x 4 = 3.14 x 16 = 50.24
the ratio of Volume of Cone to Cylinder
47.1: 50.24 = 47.1/50.24 =
Answer:
Step-by-step explanation:
You just need tp translate what is written in the two- column proof into paragraph.
Given that the two angles have same measure of 125°, by transitive property we proof that the angles are congruent.
We don't perform any of addition, division or multiplication operations. We just compare the angle measures and come to conclusion.
This is best described in the paragraph C
Answer:
A number that is greater than 0 is called a positive number
Step-by-step explanation:
Any number greater than zero is called a positive number.
On the number line, all the numbers greater than zero are to the right of zero.
In the on xy coordinate plane, a number greater than zero is located above the x-axis.
Hence the word which best completes the given statement is positive number
Hi! Multiply -0.25 by the inner numbers.
-0.25 times 84 = 21
-0.25 times -32n = -8n
Then take the -n and add that
21 -8n - n
-8n - n (or -1n) = -9n
therefore, answer would be a) 21 - 9n

Answer:
(a) 34 ft²
Step-by-step explanation:
The "top" and "back" together have a height of 2 ft + 1 1/2 ft = 3 1/2 ft. The bottom and front will have the same height, so the central vertical rectangle in the net will have a height of 2×(3 1/2 ft) = 7 ft. It is shown as having a width of 4 ft, so its area is ...
A = WH = (4 ft)(7 ft) = 28 ft²
__
The two areas labeled "left" and "right" are shown as having a height of 1 1/2 ft. Their width is the same as the width of the bottom (or top), so is 2 ft. The total area of the left and right sides is then ...
left + right = 2WH = 2(2 ft)(1 1/2 ft) = 6 ft²
That makes the area of the entire net be ...
total surface area = 28 ft² +6 ft² = 34 ft²
The surface area of the box is 34 square feet.
