Answer:
V≈4.19ft³
Step-by-step explanation:
The volume of a sphere with a radius of 1 foot is 4.19ft³.
In order to find this:
V=4
3πr3=4
3·π·13≈4.18879ft³
Answer:
a = 15
Step-by-step explanation:
Substitute b = 12 , a = 9 into the equation
12 = 
12 = 
← square both sides
144 = a² - 81 ( add 81 to both sides )
225 = a² ( take square root of both sides )
± 
= a , then
a = ± 15
a > 0 , so a = 15
(-7x² + 3) + (4x² + 2x - 1)
-7x² + 3 + 4x² + 2x - 1
(-7x² + 4x²) + (3 - 1) + 2x collect like terms
-3x² + 2x + 2
hope this helps, God bless!
Answer:
The answer would be 5 .
Bcoz in first Figure :-
12 - 9 = 3
Then ,
8 - 3 = 5
