Answer:
Approximately: 200.76π or 630.39
Step-by-step explanation:
Surface area for sphere formula: A = 4π(r^2)
36π = 4(r^2)
(36/4)π = [4(r^2)]/4
9π = r^2
28.26 = r^2 (since π equals 3.14)
√28.26 = √r^2
r ≈ 5.32
Volume for sphere formula: V = 4/3(π)(r^3)
V = 4/3(π)(5.32^3)
V ≈ 4/3(π)(150.57)
V ≈ 200.76π
or
V ≈ 630.39
Answer:ABCD and ABEC are parallelograms because they both have a pair of parallel lines.
DCE AND CEB are congruent angels
Answer:
10.49823 centimeters
Step-by-step explanation:
Simply reverse the formula for the volume of a sphere: pi*r^3*(4/3).
So: pi*r^3*(4/3)=4846.59
r^3*(4/3)=1542.71751128
r^3*4=4628.15253384
r^3=1157.03813346
r=10.49823
Answer:
x = 3
Step-by-step explanation:
Given
5x - 3 = 12 ( add 3 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
As a check
Substitute x = 3 into the left side of the equation and if equal to the right side then it is a solution.
5(3) - 3 = 15 - 3 = 12 = right side
Thus x = 3 is the solution
