Volume of sphere = 4/3 x PI x r^3
= 4/3 x 3.14 x 6^3
= 904.3 cubic meters
Volume of cone = PI x r^2 x h/3
h = √13^2-5^2 = 12
= 3.14 x 5^2 x 12/3
= 314 cubic meters
Step-by-step explanation:
let equation be y = mx + b.
m = (9- (-3))/(-4 - 2) = -2
sub (2, -3):
-3 = -2(2) + b
b = 1
therefore equation of the line is y = -2x + 1

-1.75 7/-4=-1.75 u can use a couculater
If she buys 20 tiles it will cost $23.80 and if she buys 21 it will cost $24.99
The real snowflake is 1/48th of the magnified image, so 1/48 * 18 = .375cm
