If the area of a circle is 121pi square units, what is its diameter

Mathematics

svetlana [45]2 years ago

The area of a circle is A = r^2pi
Since the area is equal to 121pi the equation would be, 121pi = r^2. To find r in terms of pi take the square root of 121, to find the radius. Then multiply that by two to get the diameter.

Find three consecutive positive integers such that the product of the first and​ third, minus the​ second, is 1 more than 7 time
Bas_tet [7]
--------------------------------------------------------------------
Define x :
--------------------------------------------------------------------
Let the smallest number be x.
First number = x
Second Number = x + 1
Third Number = x + 2

--------------------------------------------------------------------
Construct equation :
--------------------------------------------------------------------
x(x+2) - (x+1) = 7(x+2) + 1

--------------------------------------------------------------------
Solve x :
--------------------------------------------------------------------
x(x + 2) - (x + 1) = 7(x + 2) + 1
x² + 2x - x - 1 = 7x + 14 + 1
x²- 6x - 16 = 0
<span>(x+2)(x-8) = 0
</span>x = -2 or x = 8

Since x is a positive integer, it cannot be negative.
⇒x = 8

--------------------------------------------------------------------------
Answer: The three numbers are 8, 9 and 10.
