Answer:
7850 m^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi *r
314 = 2 * 3.14 *r
314 = 6.28 r
Divide each side by 6.28
314/6.28 = 6.28 r/6.28
50 m= r
Now we need to find the area
A = pi * r^2
A = 3.14 *r^2
A = 3.14 (50)^2
= 3.14 (2500)
7850 m^2
Answer: (i) 4x - 40 = 76
(ii) 29 questions
Step-by-step explanation:
Let the total number of questions be x.
Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become
4x - 40 = 76
To find the value of x , add 40 to both sides
4x = 116
divide through by 4
x = 29
Therefore , there are 29 questions on his math test
The volume of the rectangular prism is 3359232 cubic centimeters
<h3>How to determine the volume?</h3>
The length of the cube is given as:
Length, l = 12 cm
The volume of a cube is:

So, we have:

Evaluate
V = 1728
The volume of 1944 cubes is then calculated as:
Volume = 1728 * 1944
Evaluate
Volume = 3359232
Hence, the volume of the rectangular prism is 3359232 cubic centimeters

<h3>Complete question</h3>
There are exactly 1,944 of the 12 cm, or 0.5 foot cubes inside a rectangular prism. What is the volume of the rectangular prism in cubic centimeters?
Answer:
It is 16 because a square has 4 sides. 64 divided by 4 sides is 16 square centimeters per one side. Hope this helps
