Answer is =28.27433ft²

Step-by-step explanation:

A≈28.27ft²(Answer)

Diameter

Using the formulas:

A=πr2

d=2r

Solving for A

A=1

4πd2=1

4·π·62≈28.27433ft²

To answer this question we need to use a basic formula to find the area of a circle which is:
pii*radius*radius

Steps:
1. Find the radius

Divide 6 (diameter) by 2 since 2 radius makes up a diameter, so you would get 3 has the radius.

2. Substitute the values

3.14 * 3*3
Which equals 28.26.

Answer:
Exact area—28.26 ft (squared)

Rounded to the nearest tenth—28.3 ft (squared)

Hope this helps!!

For △RST and △UVW, ∠R≅∠U, ST≅VW, and ∠S≅∠v. Explain how you can prove △RST ≅△UVW by ASA

monitta

Answer:

See explanation below.

Step-by-step explanation:

Note that in △RST and △UVW

m∠T=180°-m∠R-m∠S;
m∠W=180°-m∠U-m∠V.

Since ∠R≅∠U and ∠S≅∠V, then ∠T≅∠W.

In ΔRST and ΔUVW:

∠S≅∠V (given);
∠T≅∠W (proved);
ST≅VW (given).

ASA theorem that states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

By ASA theorem ΔRST≅ΔUVW.

G(x)=-x^2-1-2x<br> f(x)=x+5<br> Find (g-f)(x)

nikitadnepr [17]

(g-f)(x) is x² - 3x - 6

<u>Step-by-step explanation:</u>

Step 1:

Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)

(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6

The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use t

iogann1982 [59]

Answer:

Mean = 4.11; Median = 4.44

Explanation:

Using a graphing calculator, enter the values into the first list. Then run one-variable statistics on the list.

By hand, to find the mean, add together all of the values:

3.25+3.25+3.66+3.83+4.57+4.52+4.74+4.69+4.44 = 36.95

Divide by the total number of data points, 9:

36.95/9 = 4.11

To find the median, order the data from least to greatest:

3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74

The middle number is 4.44.
