Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
Answer:
C. 12
Step-by-step explanation:
We know you have the number 18 and the fraction 2/3. The problem is we want to find out what 2/3 of 18 is. Well, if 18 divided by the denominator of that fraction (3) is 6 than we just add 6 because the question is asking for 2/3 NOT 1/3.
Answer: (a-b)-(2x+y)
Step-by-step explanation: The answer for number 18. (The first pair of parentheses are optional.)
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case : -1/4
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
in our case y decreases by 1 for every x increase by 4.
now, the perpendicular slope simply changes x and y upside-down and flips the sign.
in our case it is : 4/1 = 4
so, the line function in point slope form is then (using the new slope and the point coordinates)
y - 3 = 4(x - 1)
