A sphere has a diameter of 4 x 10^-3 mm. What is the approximate volume of the sphere? Use 3.14 for pi.

kolezko [41]

Answer:

$3.349 \times {10}^{ - 10} \: {mm}^{3}$

Step-by-step explanation:

$d = 4 \times {10}^{ - 3} \: mm \\ r = 2 \times {10}^{ - 3} \: mm \\ V_{sphere} = \frac{4}{3} \pi {r}^{3} \\ = \frac{4}{3} \times 3.14 \times {(2 \times {10}^{ - 3} )}^{3} \\ = \frac{4}{3} \times 3.14 \times 8\times {10}^{ - 9} \\ = \frac{100.48}{3} \times {10}^{ - 9} \\ = 33.4933333\times {10}^{ - 9} \\ = 33.49 \times {10}^{ - 9} \\ = 3.349 \times {10}^{ - 10} \: {mm}^{3}$

Seven times a number is equal to 12 more than 3 times the number. find the number.

ankoles [38]

Answer:

the number is 3

Step-by-step explanation:

seven times a number is equal to 12 more than 3 times the number

7*n = 12+3*n

7n=12+3n

subtract 3n from each side

7n-3n = 12+3n-3n

4n = 12

divide each side by 4

4n/4 = 12/4

n =3

The base of a rectangular prism has dimensions of 3 feet by 4 feet.

Ksju [112]

I'm assuming it is asking for surface area.

SA = 2(lw) + 2(hw) + 2(lh)
SA = 2(3*4) + 2(4*8) + 2(3*8)
SA = 2(12) + 2(32) + 2(24)
SA = 24 + 64 + 48
SA = 136 square feet
