Calculate the surface area of each solid with explanation ​

Mathematics
1 answer:
juin [17]2 years ago
6 0

Answer:

602.88

Step-by-step explanation:

The two lids

Area = pi * r^2

d = 12

r = d/2

r = 12/2

r = 6 cm

Area = 3.14 * 6^2

Area = 3.14 * 36

Area =  113.04

Both Lids =                                           226.08

Cylinder Body

Circumference =  2*pi*r*h

Circumference = 2*3.14 *6 * 10         <u>   376.8</u>

Total Area =                                         602.88

How do you triple rhe surface area of a cone
Gelneren [198K]
Increase the height so that the slant height triples.

For example:
  Say that lateral height is 2 and the radius is 1. The lateral surface area would be 6.28

 if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area

Hope I help :P

There are 9,481 eligible voters in a precinct. 500 were selected at random and asked to indicate whether they planned to vote fo
maria [59]

Answer:

The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

Of the 500 surveyed, 350 said they were going to vote for the Democratic incumbent.

This means that n = 500, \pi = \frac{350}{500} = 0.75

80% confidence level

So \alpha = 0.2, z is the value of Z that has a pvalue of 1 - \frac{0.2}{2} = 0.9, so Z = 1.28.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 - 1.28\sqrt{\frac{0.75*0.25}{500}} = 0.725

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 + 1.28\sqrt{\frac{0.75*0.25}{500}} = 0.775

The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.
