Answer:
Step-by-step explanation:
Let the volumes of both the spheres be
and their radii be
respectively.
(given)
![\implies\huge \frac{r_1}{r_2}= \frac{13}{9}.....(1)](https://tex.z-dn.net/?f=%20%5Cimplies%5Chuge%20%5Cfrac%7Br_1%7D%7Br_2%7D%3D%20%5Cfrac%7B13%7D%7B9%7D.....%281%29)
From equations (1) & (2), we have:
Thus, the ratio of the volumes of two spheres would be 2197 : 729.
Answer:
87.3
C=2πR ---} 2×43.668 ---} 87.336
The angles of a triangle equal 180, not 360. That means B, C, and D are all eliminated, because all of those formulas when done, the sum of the angles will be over 180 degrees. A is the only answer choice that makes sense. The answer is A.
