Anyone know this question?

Hitman42 [59]

Answer:

16π square centimeters.

Step-by-step explanation:

The area of a circle is πr².

Here, we are given the diameter, but we just need to divide it by 2 to get the radius.

8/2 = 4

So, the radius is 4 cm.

Now, we can substitute it into the formula to find the area.

π x 4²

π x 16

16π

So, the area of this circle is 16π.

Please help- Geometry question!!

The arc length of AB = 8.37 meters

Solution:

Degree of AB (θ) = 60°

Radius of the circle = 8 m

Let us find the arc length of AB.

Arc length formula:

$$\text { Arc length }=2 \pi r\left(\frac{\theta}{360^{\circ}}\right)$

$$=2 \times 3.14 \times 8\left(\frac{60^{\circ}}{360^{\circ}}\right)$

$$=2 \times 3.14 \times 8\left(\frac{1}{6}\right)$

$$=2 \times 3.14 \times 4\left(\frac{1}{3}\right)$

Arc length = 8.37 m

Hence the arc length of AB is 8.37 meters.

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs

brilliants [131]

Answer:

The slope is $s =$ $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

The weight of the rat is $w_1 = 3.5 \ pound$

The cost of feeding the rat per week is $c_1 =$ $4.50

The weight of a Beagle is $w_2 = 30 \ pound$

The cost of feed a Beagle per week is $c_2 =$ $9.20

Now the slope can be evaluated mathematically as

$s = \frac{c_2 -c_1 }{w_2 -w_1 }$

substituting values

$s = \frac{9.20 -4.50 }{30 -3.5 }$

$s =$ $0.1774 / pounds
