Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2
round
19.6 round up
20
the answer is 20 ft^2
Answer:
It is because it comes from the word 'ratio'. A rational number is usually known as the ratio of two integers, that's how it got its name. :)
The correct answer is: [A]: " 29.4 ft. "

Explanation:
___________________________________________________
Solve for "b" ; which is the "base" .
14.7 ft. = (1/2) * b ;
→ (1/2) * b = 14.7 ft ;
Multiply EACH SIDE of the equation by "2" ;
to isolate "b" on one side of the equation; & to solve for "b" ;
___________________________________________________2 * { (1/2) b } = 2 * (14.7 ft) ;
to get:
b = 29.4 ft . ;

Answer:
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of regular fares paid.
y is the number of reduced fares paid.
1,042 total fares were paid
This means that
A city bus collected $1,140 in fares on a given day. The regular fare is $1.50, and the reduced fare is $0.75.
This means that:
System of equations:
The system of equations is:
