By definition. The volume of the sphere is:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: radius of the sphere.
Substituting values:
2254 pi = (4/3) * (pi) * (r ^ 3)
Clearing the radio we have:
r ^ 3 = (3/4) * (2254)
r = ((3/4) * (2254)) ^ (1/3)
r = 11.91255883
Then, the surface area is:
A = 2 * pi * r ^ 2
Substituting values:
A = 2 * 3.14 * (11.91255883) ^ 2
A = 891.6 m ^ 2
Answer:
The surface area of the sphere is:
b. 891.6 m ^ 2

1.320 >1.302 or 1.302<1.320
Answer:
3, 12
Step-by-step explanation:
"x" is the larger number,
"y" is the smaller number.
Given
x + y = 15
x / y = 4
manipulate the equations for the problem
x / y = 4
*y *y
x = 4y
solve the system of equations by the methord of substitution:
x + y =15
4y + y = 15
5y = 15
y = 3
Subsitute back into the equations given.
x = 4y
x = 12
16 because the neg next to the subtraction sign becomes positive then you’re just adding 14+2.
