In this case, you would have to multiply 3.14 times 7. If you didn't have the diameter, and all you had was the radius, you had find half of seven, which is 3.5, multiply that by 2, and finally multiply that answer by 3.14. Hope this helps! Have a nice day :D
Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2
1024 = a^2 find the root for both sides
32 = a
Answer: 
Step-by-step explanation:
You know that the ratio of the television's screen is 
. This ratio can be also written as the following fraction:
The television shows an image with a ratio of 
which can be also written as a fraction:
Set up the following proportion and solve for "x":
Now, in order to find the percent of the screen area occupied make the following division:
Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the red car
Step-by-step explanation:
Blue car:
Travels 35 1/2 miles on 1 1/4 gallons of gasoline
Red car:
Travels 27 1/5 miles on 4/5 gallons of gasoline
We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:
Blue car:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
Red car:
(27 1/5) / (4/5) = 34 miles per gallon
The red car travels greater distance with 1 gallon of gasoline {and thats about it!}
I don't know 1 but 2 can be 2.3 over 4.5 I think sorry if it's wrong but I hope it helps
