Area of circle = π · r²
               9 π  = π · r²
                   9 = r²
                   3 = r

Volume of sphere = (4/3)π · r³
                             = (4/3)π · (3)³
                             = 4π · 3²
                             = 4π · 9
                             = 36π

Answer: the volume of the sphere is 36π

Solve for 2. Round to the nearest tenth, if necessary.
UNO [17]

Answer:

x ≈ 94.4

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan58° = \frac{LM}{KL} = \frac{x}{59} ( multiply both sides by 59 )

59 × tan58° = x , then

x ≈ 94.4 ( to the nearest tenth )
