Answer:
38.465
Step-by-step explanation:
Area of circle =
diameter= 7
radius is half of the diameter
Radius =7÷2 = 3.5
Area = 3.14 × 3.5 × 3.5
= 38.465 inch squared
I believe the answer is c
<u><em>The surface Area is multiplied by 1/4</em></u>

Answer:
it would be the first one!
Step-by-step explanation:
Answer: 19 and 31
Step-by-step explanation: Make the first number x, the second number y.
The sum of x and y is 50: x+y=50
x is 43 less than 2y: x=2y-43
replace x in equation x+y=50 with x=2y-43: 2y-43+y=50
combine like terms: 3y-43=50
add 43 to both sides: 3y=93
divide both sides by 3: y=31
replace y in equation x+y=50 with y=31: x+31=50
subtract 43 31 from both sides: x=19
the solution to the question is the first number is 19, the second number is 31
