65.97 or 65.96
follow this picture and i want you to know that sometimes if you look it up and put in the info, it will be 1 or 2 off. sometimes it’s right. the actual formula for finding volume is V= 1/3h(pi)r and to the second power. if we do it this way, we would do 1/3 x H or 1/3 x 7.
1/3 x 7 is 2.3
2.3 x 3.14 is 7.2
7.2 x 3 is 21.6
21.6 to the second power is 466.56
now i have no clue if i did this right but i will let you follow your instinct and whatever anyone else says! i’m sorry if this isn’t helpful but i tried by best at describing :)
the first question mark is 6 and the second question mark is 26 (the square root)
