Answer:
511.8 cubic inches
Step-by-step explanation:
The volume of a sphere is given by ...
V = (4/3)πr³ = (4/3)π(d/2)³ = (π/6)d³ . . . . where d is the diameter
Assuming the dimension of the cube-shaped box is d, the diameter of the ball, the volume of the box will be d³. So, we have ...
85.3π = (π/6)d³
(85.3π)(6/π) = d³ . . . . . the volume of the box
(85.3)(6) = d³ = 511.8 . . . . cubic inches
The volume of the smallest box is 511.8 cubic inches.
He has 20 pencils.
The ratio in the problem is 4 pens to 5 pencils meaning for every 4 pens there are 5 pencils.
So take this into mathematics 16pens/4pens = 4
5pencils * 4 is equal to 20 pencils
the ratio still works and it is still 4 to 5 so the answer is 20...pencils.
Answer:
D
Step-by-step explanation:
Because 88 minus 82 equals 6
V = π × r² × h
The radius of the base is equal to half of its diameter. So, we have:
V = 3,14 × 6,5² × 11
V ≈ 1459.3 cm³
