A circle has a diameter

torisob [31]

The circumference of circle is 20.096 units

Solution:

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

The distance between two points is given by formula;

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

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

The circumference of the circle is given by formula:

$c = \pi d$

Where "d" is the diameter of circle

$c = 3.14 \times 6.4 = 20.096$

Thus circumference of circle is 20.096 units

Ellen has 20 feet of ribbon. She use12 feet of the ribbon to make pillows. She gives 1/4 of the ribbon to her friend. How many i

slamgirl [31]

Answer:

Ellen gave 24 inches of her ribbon to the friend.

Explanation:

The total length of ribbon Ellen has = 20 feet

Used to make pillows = 12 feet

Remaining ribbon = 20-12 = 8 feet

Given to her friend = 1/4

1/4 of 8 = 1/4 × 8 = 2 feet

so she gave 2 feet of ribbon to her friend.

As there are 12 inches in 1 foot.

2 feet in inches = 24 inches

Therefore, Ellen gave 24 inches of her ribbon to the friend.

Margarita [4]

Answer: b. Orchid mantises tend to be advantaged in habitats that remain constant; the rain forest habitat is likely to shift because of global climate change.

Explanation:

The orchid mantis is a predator in South East Asia that camouflages itself as an orchid to catch its prey.

While the tropical cockroach is a more hardy specie, the optimum habitat for orchid mantises is one with limited variation in temperature, moisture and humidity. Therefore, as temperatures increase and climate change results in severe weather changes, it will lead to adverse effects on orchid mantises.
