b)1650.23
c)2356.23
d)2556.12
Q.55)Compute standard deviation for the following
data : 1, 2, 3, 4, 5, 6, 7
a) 2
b)5
c)3
d)4​

Answer 1

Answer: $1437.33 cm^3$

Step-by-step explanation:

Surface area of Sphere = 4πr²

4πr²=616

πr²=616/4

πr²=154

r²=154×7/22

r²=7×7

r=7

Volume of sphere = 4/3πr³

=4/3×22/7×7×7×7

=4312/3

=$1437.33 cm^3$
