Answer:
- A) The radius of the sphere is 3 millimeters.
- B) The circumference of the sphere is 6π millimeters.
Step-by-step explanation:
Based on the answer selections, it appears we need to find the radius and circumference of the sphere. We can start with the volume formula in terms of the radius:
V = (4/3)πr³
36π = (4/3)πr³
(36π)(3/(4π)) = r³ = 27 . . . . . . mm³
r = ∛27 = 3 . . . . mm³
Then the circumference is ...
C = 2πr = 2π(3 mm) = 6π mm
The radius is 3 mm; the circumference is 6π mm.
Answer:14.4In^3
Step-by-step explanation:
Diameter=3.8In
radius(r)=3.8 ➗ 2=1.9In
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x(1.9)^3
Volume=2/3x3.14x1.9x1.9x1.9
Volume=(2x3.14x1.9x1.9x1.9) ➗ 3
Volume=43.07452 ➗ 3
Volume=14.4In^3
Answer: x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−7x=31
−4+−7x=31
−7x−4=31
Step 2: Add 4 to both sides.
−7x−4+4=31+4
−7x=35
Step 3: Divide both sides by -7.
−7x
−7
=
35
−7
x=−5
5 to 10 is just one of many examples. Hope this helps :)
