Answer:

The correct answer is A on Edge 2020.

Step-by-step explanation:

A sphere has 2/3 the volume of a cylinder given that the radius and height are equal. Because the volume of the cylinder is 27 pi (on Edge 2020), you need the equation: 2/3(27 pi) or A.

Law of cosine. Please help

Anna35 [415]

Answer:

B) 41.7

Step-by-step explanation:

Let $a=25$ , $b=32$ , and $c=37$ . Use the Law of Cosines equation to find angle A=x which is directly across from side $a$ :

$\displaystyle \cos(A)=\frac{b^2+c^2-a^2}{2bc}\\ \\\cos(A)=\frac{32^2+37^2-25^2}{2(32)(37)}\\ \\\cos(A)=\frac{1024+1369-625}{2(1184)}\\\\\cos(A)=\frac{2393-625}{2368}\\ \\\cos(A)=\frac{1768}{2368}\\\\A=\cos^{-1}\biggr(\frac{1768}{2368}\biggr)\\ \\A\approx41.7^\circ$

Therefore, the correct answer is option B, which means you were right!
