You plug in 841pi to the area equation.
841pi=pi(r)^2
You already know pi so u can take that out to find the radius.
841=r^2
r=29
Now you have the radius and can find the circumference.
Plug numbers in
C=2(pi)(29)
C=58pi
Hope this helped and sorry if I am wrong!! If you need further explanation you can ask.

. Find four consecutive odd integers such that the sum of the first and fourth is 55 greater than the opposite of the third.
Setler79 [48]

Answer:

The four consecutive odd integers = 15, 17, 19, 21

Step-by-step explanation:

Four consecutive odd integers in Mathematics when x is an integer is given as:

x , x + 2 , x + 4, x + 6

Where:.

First integer = x

Second integer = x + 2

Third integer = x + 4

Fourth integer = x + 6

The sum of the first and fourth is 55 greater than the opposite of the third

Hence :

x + x + 6 = -(x + 4) + 55

x + x+6 = (-x - 4) + 55

2x + 6 = -x + 51

Collect like terms

2x + x = 51 - 6

3x = 45

x = 15

Therefore,

First integer = x = 15

Second integer = x + 2 = 15 + 2 = 17

Third integer = x + 4 = 15 + 4 = 19

Fourth integer = x + 6 = 15 + 6 = 21

The four consecutive odd integers = 15, 17, 19, 21

You are the manager of a monopoly. A typical consumer's inverse demand function for your firm's product is P = 250- 4Q, and your
kondor19780726 [428]

Answer:

(1) 240-8Q=0240−8Q=0  (2) 225 (3) it is very necessary that the direct elasticity of demand for a product at a price from several buyers be different significantly;  so that customers are easily known, that further goods resale by buyers is not possible

Step-by-step explanation:

Solution

Given that:

(1) TR=∫MR=250Q−4Q  

Pr=TR-TC=250Q-4Q² - 10Q=240Q−4Q²  

Thus,

Pr   =240−8Q

240-8Q=0240−8Q=0

(2) Q=30

Now,

p=250-4 * 30=130

p=100

so.

100=250−4Q

Q=37.5

Pr=240×37.5−4×37.5²

=3375

Hence,

ΔPr=3600−3375=225

(3) For the execution of price discrimination by a monopolist, it is very important that the direct elasticity of demand for a product at a price from different buyers be remarkably different; so that  customers are easily known, that further goods resale by buyers is not done.
