Answer:
separate and square both the top and bottom
the square of square root three is just 3 and the square of 3 (the bottom of the fraction) is 9
so now you have 3(i^2) /9
you can simplify this by three and then i^2 is -1
you now have -1/3 and thats the final answer
Im gonna asume you mean side, so 1 foot = 12 inches (:
The correct answers are:
Exact volume =

in^3
Approximate volume = V = 33.51 in^3
Explanation:The volume of the sphere is:

Since r = 2 in
Hence

in^3
(exact)
V = 33.51 in^3 (approximate)
Im not sure what the answer is but dont open the link its a virus
Answer:
A. 1.5 cm by 2.5 cm
B. 27 cm by 45 cm
C. 9 cm by 15 cm
D. 30 cm by 50 cm
Step-by-step explanation:
The dimensions of the original painting = 12 cm by 20 cm painting
Hence, the proportion is:
12/20 = 0.6
Hence, we compare the options given in the question.
A. 1.5 cm by 2.5 cm
= 1.5/2.5 = 0.6 , option A is correct
B. 27 cm by 45 cm
27cm/45 cm = 0.6 Option B is correct
C. 9 cm by 15 cm
9cm/15cm = 0.6 , Option C is correct
D. 30 cm by 50 cm
30 cm /50 cm = 0.6 Option D is correct
E. 6 cm by 14 cm
6cm/14 cm = 0.4285714286
Option E is not correct
Therefore, Options A to D are the correct options
