Answer:

<em>Circumference:</em> 18.84 cm

<em>Area:</em> 28.26 cm^2 (exponent 2)

Step-by-step explanation:

Circumference = 2(pi)r

The diameter is 6. Means the radius is 3 (half of 6)

pi = 3.14

2(3.14) x 3 = 18.84

Circumference is 18.84 cm.

Area of a circle = (pi)r^2

(3.14)(3)^2 = 28.26 cm^2 (exponent 2)

Dan Perkins goat is attached to the corner of the 8-foot-by-4-foot pump house by QN 8-foot length of rope. The goat eats the gra
SashulF [63]
The goat is tied in the four corners of an 8-foot by 4-foot pump house. The rope is 8 feet. The goat is eating the grass, forming a circle The pattern is 3/4 of a circle radius 8 and 1/4 of a circle radius 4.

Getting the area of radius of 8 feet
Area = pi * r^2
Area = pi * 8^2
Area = 201.06 feet^2

Getting the area of radius of 4 feet
Area = pi * r^2
Area = pi * 4^2
<span>Area = 50.27 feet^2
</span>
3/4 of 201.06 = 150.80 feet ^2
1/4 of 50.27 = 12.60 feet^2

So the total area is 153.40 feet^2

The following functions give the populations of four towns with time tt in years.
expeople1 [14]

Solution :

Transforming given equations :

1)\ P = 600( 1 + \dfrac{12}{100})^t\\\\2)\ P = 1000( 1 + \dfrac{3}{100})^t\\\\3)\ P = 200( 1 + \dfrac{8}{100})^t\\\\4)\ P = 900( 1 - \dfrac{10}{100})^t

From above equations we can see that equation 1) has largest percentage growth rate and the percent growth rate is 12% .

Hence, this is the required solution.
