Surface area of sphere equals its four radii squared multiplied by the number π.
We have then:
A = 4 * π * R ^ 2
Substituting:
804 = 4 * π * R ^ 2
Clearing the value of R we have:
R = root (804 / (4 * π))
R = 7.99876785 cm
Nearest whole number:
R = 8 cm
Answer:
The radius of a sphere is:
B. 8cm

Answer:
=x+22
-by-step explanation:
Let's simplify step-by-step.
3(x+4)+2(5−x)
Distribute:
=(3)(x)+(3)(4)+(2)(5)+(2)(−x)
=3x+12+10+−2x
Combine Like Terms:
=3x+12+10+−2x
=(3x+−2x)+(12+10)
=x+22
