Answer:
V ≈ 258 ft³
Step-by-step explanation:
I given the diameter d= 7.9 ft so the radius is r = d/2 = 7.9/2 ft
Volume of a sphere is
V = (4/3) π·r³ = (4/3) · π · (7.9/2)³ = 258.1546167 ft³

Answer:
9
Step-by-step explanation:
Compare your x2 + y2=81 to the following:
x^2 + y^2 = 81
The " ^ " symbol indicates exponentiation.
Now compare x^2 + y^2 = 81 to
x^2 + y^2 = r^2.
This is the standard equation of a circle of radius r centered at the origin, (0,0). You can see for yourself that 81 must equal r^2.
Taking the square root of 81, we get plus or minus 9.
But the radius must be positive, so we reject the -9 and take +9.
The radius is 9.
