What is the best approximation for the area of a circle with a diameter of 13 meters?

1 answer:

4 0

First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5

Second, use the equation A=pi * r^2 to find the area of the circle.
A=(3.14) * (6.5^2) = 132.665m^2

so the answer is 132.7 m^2.

(-6,-4) and is parallel to the line x+6y=12

HACTEHA [7]

Answer: y = $-\frac{1}{6}x-5$

Step-by-step explanation:

x+6y=12

6y=-x+12

y=- $\frac{x}{6}$ + 2

If its parallel it means that the slope will be the same

y = mx + b

-4 = -1/6 * (-6) + b

b = -5

Thus,

y = -1/6 x - 5

Help its 11:28 due at 11:59 :((

Alja [10]

Answer:

y = 0.87x + 0.02

Step-by-step explanation:

Euros as a function of dollars means that euros is y and dollars are x.

We are given 2 points: (4, 3.5) and (10, 8.72)

slope = (8.72 - 3.5)/(10 - 4)

slope = 5.22/6 = 0.87

y = 0.87x + b

3.5 = 0.87(4) + b

b = 0.02

y = 0.87x + 0.02

If f(x)= x^1/2 - x and g(x)= 2x^3 - x^1/2 - x, find f(x) - g(x)

Pavlova-9 [17]

Answer:

$-2x^3+2x^{1/2}$

Step-by-step explanation:

First, you have to substitute both functions into the equation to get:

$f(x)-g(x) = (x^{1/2}-x) - (2x^3-x^{1/2}-x)$

Then, you distribute the negative sign in front of g(x) to get:

$= x^{1/2} - x -2x^3+x^{1/2}+x$

And finally, you add/subtract the x's that have the same power to get:

$=-2x^3+2x^{1/2}$
