The formula for the area of a circle is A = πr2, where A = area and r = radius.
BaLLatris [955]

The area of a circle with radius of 5 feet is 25π square feet

Step-by-step explanation:

The area of a circle is found out using the formula

A = \pi r^2

Here A is the area

r is the radius of the circle and

pi is a constant

given

Radius = r = 5

We have to find the area in terms of pi

So,

A = \pi r^2\\Putting\ r=5\\A = \pi *(5)^2\\A = 25\pi\ square\ feet

Hence,

The area of a circle with radius of 5 feet is 25π square feet

Keywords: Area, radius

Perform the indicated operations(7n^2 - 6) - (6n^2 + 9) - (7n + 6)
DerKrebs [107]

Answer:

n²-7n-21

Explanation:

Given the expression:

\mleft(7n^2-6\mright)-(6n^2+9)-(7n+6)

First, open the brackets:

=7n^2-6-6n^2-9-7n-6

Next, bring the like terms together and simplify:

\begin{gathered} =7n^2-6n^2-7n-6-9-6 \\ =n^2-7n-21 \end{gathered}

ACCTUALLY HELP ME??!!!!!!! NEEDED FOR TOMORROW AND 50 POINTS! will award brainliest for first answer!!
drek231 [11]

Answer:

a:c = 35:24

a:c = 20:27

a:c = 35:22

a:c = 28:27

Step-by-step explanation:

a:b = 7:3

Using cross products

3a = 7b

Divide by 7

3a/7 = b

Now we want

8b = 5c

Substitute in 3a/7 for b

8 (3a/7) = 5c

24/7a = 5c

Multiply by 7

24/7a *7 = 5*7c

24a = 35c

Divide by c

24 a/c = 35

Divide by 24

a/c = 35/24

a:c = 35:24

a:b = 4:9

Using cross products

9a = 4b

Divide by 4

9a/4 = b

Now we want

3b = 5c

Substitute in 9a/4 for b

3 (9a/4) = 5c

27/4a = 5c

Multiply by 4

27/4a *4 = 5*4c

27a = 20c

Divide by c

27 a/c = 20

Divide by 27

a/c = 20/27

a:c = 20:27

b:c = 5:11

Using cross products

11b = 5c

Divide by 11

b = 5c/11

Now we want

2a = 7b

Substitute in 5c/11 for b

2a = 7(5c/11)

2a = 35c/11

Multiply by 11

2a*11 = 35c

22a = 35c

Divide by c

22 a/c = 35

Divide by 22

a/c = 35/22

a:c = 35:22

b:c = 14:3

Using cross products

3b = 14c

Divide by 3

b = 14c/3

Now we want

9a = 2b

Substitute in 14c/3 for b

9a = 2(14c/3)

9a = 28c/3

Multiply by 3

9a*3 = 28c

27a = 28c

Divide by c

27 a/c = 28

Divide by 27

a/c = 28/27

a:c = 28:27
