Answer:
See attachment. Also, I got 2.36 as the answer with my calculator despite that not being on the multiple choice list
Although I am not clear as to whether the radius is r—1 or otherwise, but if i work with the values i see then:
Volume — T. S. A.
= πr²h — (2πr²+2πrh)
So after the simplification, I substitute the values given,
r= r—1 and h=h—1
And the answer is...
π(r—1)(rh—3r—3h+5)!
Answer:
54/5
Step-by-step explanation:
5(x+10)-25=54+25
5x + 50 - 25 = 54 + 25
5x + 50 - 25 = 79
5x + 25 = 79
5x = 79 - 25
5x = 54
x = 54/5
