Answer:
i think it's circumference
Step-by-step explanation:
Answer:
<h2>The circumference is multipled by 4.</h2>
Step-by-step explanation:
The formula of an area of a circle"
The formula of a circumference of a circle:
The area multipled by 16:
The radius has increased fourfold, therefore:
The circumference is multipled by 4.
You can calculate the area and check the circumference:
Calculate the radius:
<em>divide both sides by π</em>
Calculate the circumference of both circles:
Answer:
The equation of the line that passes through the points
(-20,18) and (30,14)
is
y=-2/25x+82/5
This could be wrong because I'm going into the fifth grade but wouldn't it just be (7,-3)?
Answer:
x = 3
Step-by-step explanation:
(x - 1)2 = 4
how to get this solved is very simple.
first step to apply is the BODMAS RULE
B..................... bracket
O..................... of
D.....................Division
M.................... multiplication
A..................... addition
S.................... Subtraction
so (x - 1)2 = 4
we have,
2x - 2 = 4 ( by opening the bracket)
collect the like terms
2x = 4+2
divide both sides by 2
2x/2 = 6/2
x = 3
to check if your answer is correct put the value of x = 3 into the question and see if the right hand side will equal to the left handside
(x - 1)2 = 4
(3-1)2=4
2(2)=4
4=4.............................. proved
