If the circumference of a circle measures 25.12cm, what is the area of the circle in terms of pi?

Mathematics
1 answer:
kiruha [24]3 years ago
4 0

Answer:

Step-by-step explanation:

The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.

Circumfrance is 25.12 so....

25.12 = 2 * (pi) R........ you want to find R because you need it to find the area

R is about 4; it is 3.99797 .

You use the R that you goot from cirdumfrance to find area.

Area = (pi) (4)^2 = 50. 265

or is you prefer a more precise answer, Area = 50.2145

Find the average rate of change of f(x)=2x^2-7x from x=2 to x=6
scoundrel [369]

Answer:

Step-by-step explanation:

The average rate of change of a function f between a and b (a< b) is :

R =[f(b)-f(a)] ÷ (a-b)

●●●●●●●●●●●●●●●●●●●●●●●●

Let R be the average rate of change of this function

f(6) = 2×6^2 - 7×6 = 72-42 = 30

f(2) = 2×2^2 - 7×2 = 8-14 = -6

R = [f(6) - f(2)]÷ (6-2)

R = [30-(-6)] ÷ 4

R = -36/4

R = -9

■■■■■■■■■■■■■■■■■■■■■■■■■

The average rate of change of this function is -9

GREYUIT [131]

Answer:

a) We can just add Distance from Tulsa to Dallas and distance from Dallas to Houston,

258 + 239 = 497

b) It's the same distance = 497

c) We can tell its the same distance, because we are travelling in the same road, which would mean it would be no different when going to or coming back from Houston.
