Question:

Use the formulas below to find the surface area and volume of the cube, sphere, and cylinder “ice cubes”.

“Ice cube” measurements:

• Cube: s = 3 cm

• Sphere: r = 1 cm

• Cylinder: r = 2 cm and h= 3 cm

Note: After you find the surface area and volume of each shape, divide the surface area by the volume to find the surface area to volume ratio expressed as a single number. This should go in the last column.

Answer:

Cube:

Surface area = $6s^2$

Surface area = 6 (3)(3)

Surface area = $54 cm^2$

Volume = $s^3$

Volume = $(3)^3$

Volume = $27 cm^3$

Surface Area to Volume Ratio = $\frac{54}{27}$ = $\frac{2}{1}$ = 2:1

Sphere:

Surface area = $4\pi r^2$

Surface area = $4 \pi (1)(1)$

Surface area = $12.566cm^2$

Surface area = $13 cm^2$ (rounding off )

Volume = $\frac{4}{3} \pi r^3$

Volume = $\frac{4}{3} \pi (1)^3$

Volume = $4.188 cm^3$

Volume = $4 cm^3$ (rounding off )

Surface Area to Volume Ratio = $\frac{13}{4}$ = 13 : 1

Cylinder:

Surface Area $= 2\pi r^2 + 2 \pi rh$

Surface Area = $2\pi (2)^2 + 2 \pi (2)(3)$

Surface Area = $2\pi (4) + 2 \pi (6)$

Surface Area = $8 \pi + 12 \pi$

Surface Area = $20 \pi$

Surface Area = $62.83 cm^2$

Surface area = 63 $cm^2$ (rounding off )

Volume = $\pi r^2 h$

Volume = $\pi (2)^2 (3)$

Volume = $\pi (4) (3)$

Volume = $12 \pi$

Volume = 37 .699

Volume = 38 $cm^3$

Surface Area to Volume Ratio = $\frac{63}{38}$ = 68 : 38

Do you think there should be a data base for everyone's DNA ? If so then why?

Schach [20]

Answer:

yes

Explanation:

Given set data base has every new born child's DNA towards every passing of every other. Not meaning habing a crimjnal record puts blood and suliva but preamble DNA from birth, now rather than having to point match on criminal data, rather pre-set DNA data base on every human living or non-living.

Properly deviding DNA base still into split sections for criminal records amd clean records where clean record's are rather added/stamped when found guilty in the court of law, but then having all possible DNA sample at the touch of a button (rather should i say match) pre-liminates playing detective and running around following leads, ensuring closure towards deceased members familiy and aswell as eliminating wrongful imprisonment of non guilty members that adds unnecessary cost and reclurces towrards goverment funds etc.

Having "system that works, why fix" is not as having a system that continuously improves and sustains a flawless lrocedure rather than groping at the mids of a cold case in the hope that somewhere a light switch gets turned or a whistleblower apears is high waist of reacources and complete over kill. Given we are in a modern time where tech constantly improves to ease the human race, why not sustain a even rise in our modern living standards and consecutive growth in a that's even the slightest of possibilities.
