Explain how an increase of the annual melt season in Antarctica can have global effects.

zysi [14]

Answer:

A longer melt season in Antarctica leads to a greater loss of land-based glacier ice. The water from the melted land glaciers runs into the oceans and leads to an overall increase in volume. This change has global effects.

A circle has a diameter

torisob [31]

The circumference of circle is 20.096 units

<em><u>Solution:</u></em>

Given that circle has a diameter with endpoints at (10, 8) and (5, 4)

To get the diameter, find the distance between the end points

<em><u>The distance between two points is given by formula;</u></em>

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Here the points are (10, 8) and (5, 4)

$(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)$

Substituting the values we get,

$\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}$

$d = \sqrt{41} = 6.4$

Thus the diameter is 6.4 units

<em><u>The circumference of the circle is given by formula:</u></em>

$c = \pi d$

Where "d" is the diameter of circle

$c = 3.14 \times 6.4 = 20.096$

Thus circumference of circle is 20.096 units
