Find the distance between the pair of points given on the graph. Distance = √ (blank)

kozerog [31]

Answer:

√2.236

Step-by-step explanation:

(2,0) (5,-2). 2 - 5 = -3. 0 - -2 = 2. -3 squared = -9. 2 squared = 4. -9 + 4 = -5. Square root of -5 = 2.236, so the distance would be √2.236

The area of a circle is 100π ft². What is the circumference, in feet? express your answer in terms of \piπ

Bond [772]

Answer:

20π ft

Step-by-step explanation:

To find the circumference of the circle given its area, first find its radius.

$\textcolor{steelblue}{\boxed{\text{Area of circle =}\pi {r}^{2} }}$

Substitute given area into the formula:

100π= πr²

Divide both sides by π:

100= r²

Square root both sides:

$r = \sqrt{100}$

r= 10 ft

$\textcolor{steelblue}{\boxed{\text{Circumference of circle = }2\pi {r}}}$

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.

Circumference of circle

= 2(π)(10)

= 20π ft
