Answer:
Step-by-step explanation:
The surface area of a sphere with radius r is given by
S = 4 pi r^2
for a radius of 11 units,
S = 4 pi 11^2 = 484 pi = 1520.5 sq. units
This does not correspond to any of the answers.
Please check question.
All of the above are true
Answer:
Step-by-step explanation:
Required
Which equals
Collect like terms
Divide both sides by 2
Collect like terms
Divide both sides by 2
Collect like terms
Divide both sides by -2
Divide both sides by 2
Collect like terms
Divide both sides by 2

Hence, the equations with the required solution are:
A = L x W
L = W + 3
so equation
A = W (W + 3)
70 = W (W + 3)
or
W (W + 3) = 70
answer
D. last one
W (W + 3) = 70
