C = Pi x diameter.
C = 3.14 x 2
C = 6. 28

A = Pi x radius^2 
Radius = 1/2diameter
Radius = 1
Area = (3.14)(1^2)
Area = 3.14

Finding the area and circumference of a circle is pretty easy, actually. You just need to be comfortable with the formulas. Hope this helped!

Circumference: 6.28 feet ~rounded to the nearest hundredth

To find circumference, multiply the diameter by pi.

Area: 3.14 feet squared ~rounded to the nearest hundredth

To find area, divide the diameter by 2 and multiply by pi.

Using the information that you've provided, I would say that Mr. Banks drove home at 5:15, but if you're asking what time he arrived home that would be at 6:30. :))

Two rectangular lawns are similar shapes.
Reil [10]

Answer:

The answer to your question is Area = 37500 ft²

Step-by-step explanation:

Data

lawn 1                                       lawn 2

width = 550 ft                          width = 250 ft

Area = 181500 ft²                     Area = ?

Process

1.- Find the length of lawn 1

Area = length x width

-solve for length

length = Area/width

-Substitution

length = 181 500 ft²/ 550

-result

length = 330 ft

2.- Find the length of lawn 1 using ratios and  proportions

                     550 : 330 :: 250 : x

                      x = (250 x 330) / 550

                      x = 150 ft

3.- Find the area of lawn 2

-Substitution

Area = 250 x 150

-Result

Area = 37500 ft²

Answer:

January has the greater MAD.

Step-by-step explanation:

The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.

If s(x)=2-2x^2 and t(x)=3x, which value is equivalent to (s•t)(-7)?
bazaltina [42]

Answer:

Step-by-step explanation:

Answers

-439

(s o t)(x)=s(t(x))

(s o t)(-7)=s(t(-7))

x=-7→t(-7)=3(-7)→t(-7)=-21

(s o t)(-7)=s(t(-7))=s(-21)

x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439

(s o t)(-7)=s(t(-7))=s(-21)=-439

Answer: Option A -439
