Find the surface area and volume. Answer SA = ____, V= _______
Tomtit [17]

Answer:

SA = 251.33 yd ^2

V = 301.59 yd ^3

Step-by-step explanation:

Right cylinder   2π  = 6.28318530718

Solve for surface area

A =2πrh+2πr2  = 24 x 2π + 2π x 16

A =150.796447372 + 100.530964915

A ≈251.33 yd^2

Right cylinder π = 3.14159265359

Solve for volume

V = πr2h = 16 x 6 = 96π

V = 3.14159265359 x 96

V = 301.592894745

V= 301.59 yd ^3

Li Wei has several streams of income, as shown in the table. Some streams are active income and some are passive.
WARRIOR [948]

Based on the streams of income that Li Wei has, we can calculate that he has a total passive income of <u>$3,010.</u>

Passive income refers to income that is made without a person actively involving themselves in the activity generating the income.

In this scenario, the passive income sources are:

  • Stock dividends
  • Business investment interest
  • Royalties from a novel

Total passive income therefore is:

= 530 + 1,080 + 1,400

= $3,010

In conclusion, the total passive income is $3,010.

The radius of a circle is measured at 15.6cm. The actual radius is 15.3cm. Find, to the nearest percent, the percent error in th
Anon25 [30]

Answer:

Percentage\hspace{3}error\approx 1.96\%

Step-by-step explanation:

The error percentage is a measure of how inaccurate a measurement is, standardized based on the size of the measurement. It can be easily calculated using the following formula:

Percentage\hspace{3}error=|\frac{v_A-v_E}{v_E} | \times 100

Where:

v_A=Approximate\hspace{3}value\\v_E=Exact\hspace{3}value

Therefore, according to the data provided by the problem:

v_A=15.6\\v_E=15.3

The percentage error is:

Percentage\hspace{3}error=|\frac{15.6-15.3}{15.3}| \times 100 = 1.960784314\%\approx 1.96\%
