C= pi•diameter. If the dinner plate's diameter is 7 inches, then multiply 7 times pi, 3.14. 7•3.14= 21.98. So, the answer for the first question is B, 22. :) 

For the second question, it is asking for the answer in terms of pi. Since the diameter is 6, divide 6 by 2 to get the radius. (A=pi•radius squared) 6 divided by 2 is 3. Now, square 3. which gives you 9. Since the answer has to be in terms of pi, the answer is B. ;)

Question 1:
---------------------------------------------
Given information
---------------------------------------------
Diameter = 7 inches

---------------------------------------------
Find Circumference
---------------------------------------------
Circumference = πD
Circumference = π x 7
Circumference = 22 inches (nearest inches)

---------------------------------------------
Answer: 22 inches
---------------------------------------------


Question 2:
---------------------------------------------
Find Radius
---------------------------------------------
Diameter = 6 feet
Radius = 6 ÷ 2
Radius = 3 feet

---------------------------------------------
Find Area
---------------------------------------------
Area = πr²
Area = π x 3 x 3 
Area = 9π ft²

---------------------------------------------
Answer: 9π ft² (Answer B)
---------------------------------------------

Question 3:

---------------------------------------------
Given information
---------------------------------------------
Area = 144 in²

---------------------------------------------
Formula
---------------------------------------------
Area of Square = Length x Length

---------------------------------------------
Apply Formula
---------------------------------------------
144 = Length x Length
Length² = 144
Length = √144
Length = 12

---------------------------------------------
Answer : 12 inches (Answer A)
---------------------------------------------

What is the area of this composite figure?
jek_recluse [69]

Answer:

7.14 in. sq

Step-by-step explanation:

First find the area of the square; 2x2=4

Now find the area of the semi-circle; radius = 1.    

1 squared= 1 Now multiply by 3.14 which equals 3.14

Now divide by 2 because it's a semi-circle, you get 1.57.

Multiply 1.57 by 2 because you have 2 semi-circles, the would equal 3.14

Add 4+3.14 and you get 7.14

The area of the composite figure is 7.14 in. sq

A driver who drives at a speed of r mph for t hr will travel a distance d mi given by dequalsrt mi. How far will a driver travel
liubo4ka [24]

Answer:

At a speed of 57 mph for 8 hr a driver will travel 456 mi

Step-by-step explanation:

Here we have a summary of the letters for each variable:

Speed ---> r          (in units of mph)

Time ---> t            (in units of hr)

Distance ---> d     (in units of mi)

These three variables are related by the next formula:

d = rt

In the data they give to you: 57 mph and 8 hr, they are telling you the r and the t, respectively:

r = 57 mph

t = 8 hr

The only thing you have to do is replace the values:

d = rt    ---->     d = 57 mph x 8 hr

                        d = 456 mi

Compare the functions.
marshall27 [118]

Function h has the largest y-intercept which is 44

Step-by-step explanation:

Any linear function is represented in the form

f(x) = mx+b

Here b is the y-intercept of the linear function i.e. the constant term in the function.

We will compare all the functions with the general form we get

y-intercept of f(x) = 1

y-intercept of g(x) = 8

y-intercept of h(x) = 44

y-intercept of j(x) = 0

Hence,

Function h has the largest y-intercept which is 44
