Answer:
12,500,000. You simply move the decimal point over to the right 7 times.
Answer:
21.99115 ≈ 22 cm
Step-by-step explanation:
1) So basically in the problem, they give you 7 cm as the diameter.
2) The circumference formula is C = 2πr (if they give you a radius) or C = πd (In this case, this would be the formula to use.)
3) Plug in; C = π(7) = 21.99114858 ≈ 22 cm
Answer:
92.11 cm³
Step-by-step explanation:
The figure below;
- Has two hemispheres, and
- An open cylinder
- The radius of the hemisphere is 2 mm
- The height of the cylinder is 6 mm (10 mm - 4 mm)
We are required to determine the volume of the figure;
The volume of a hemisphere is given by;
Volume hemisphere = 2/3πr³
Taking π to be 3.14
The Volume of the two hemisphere;
= 2/3 × 3.14 × 2³
= 16.75 cm³
Volume of the cylinder;
Volume = πr²h
= 3.14 × 2² × 6
= 75.36 cm³
Thus, volume of the figure;
= 16.75 cm³ + 75.36 cm³
= 92.11 cm³
Hence, the volume of the figure is 92.11 cm³
Answer:
0.3
Step-by-step explanation:
total:16.3
20*0.8=16 (amount she will use)
16.3-16=0.3
