A block of steel in the shape of a prism with a rectangular base. The measurements of the base are 30 cm by 20 cm and the height of the prism is 10 cm. By melting this block, marbles are made which have the shape of a ball. How many marbles can be made if the radius measurement of one of these marbles is 11.273 cm?
Can anyone please help?
Answers
9514 1404 393
Answer:
1 marble
Step-by-step explanation:
The volume of steel is ...
V = LWH
V = (30 cm)(20 cm)(10 cm) = 6000 cm³
The volume of a marble is ...
V = (4/3)πr³ = (4/3)π(11.273 cm)³ = 6000 cm³
The block of steel will make 1 marble.

Find the length of the third side. If necessary, write in simplest radical form 8 5
Answers
Answer: c = [tex]\sqrt{89}[/tex]
8² + 5² = c²
64 + 25 = c²
[tex]\sqrt{89}[/tex] = [tex]\sqrt{c^{2} }[/tex]
[tex]\sqrt{89}[/tex] = c
The length of the third side is 9.4.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
Applying Pythagorean theorem.
Third side = x
x² = 8² + 5²
8 x 8 = 64 and 5 x 5 = 25
So,
x² = 64 + 25
x² = 89
x = √89
x = 9.4333
Rounding to the nearest tenth
x = 9.4
Thus,
The length of the third side is 9.4.

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.

Of the shapes shown, 1/3 are circles and 1 1/2 are rectangles. What fraction of the shapes are either circles or rectangles?
Answers
Answer: 1 5/6
Step-by-step explanation:
From the question given, we are told that out of some shapes shown, 1/3 of the shapes are circles and 1 1/2 are rectangles.
The fraction of the shapes that are either circles or rectangles, will be gotten by adding the shapes that are circle to those that are rectangle. This will be:
= 1/3 + 1 1/2
We should make the fraction have a common denominator.
= 2/6 + 1 3/6
= 1 5/6
The answer is 1 5/6.
