Answer:

r = \sqrt{\frac{A}{\pi } }

r = 17.2 cm

Step-by-step explanation:

∵ The area of the circle A = πr²

∴ r² = A/π

∴ r = √(A/π)

∵ A = 54 cm²

∵ π = 22/7

∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm

charle [14.2K]

The probability that she will obtain a scholarship given that she is accepted by the college is 0.54.

Given that the probability that Samantha will be accepted by the college of her choice and obtain a scholarship is 0.35, to determine, if the probability that she is accepted by the college is 0.65, the probability that she will obtain a scholarship given that she is accepted by the college, the following calculation must be performed:

  • 0.65X = 0.35
  • X = 0.35 / 0.65
  • X = 0.538

Therefore, the probability that she will obtain a scholarship given that she is accepted by the college is 0.54.

La suma del cuadrado de un número más el triple del mismo número es igual a dieciocho. Encuentra dicho número.
Genrish500 [490]

If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6

Let the unknown number be x

The square of the number is expressed as x²

Triple of the unknown number will also be expressed as 3x

Taking the sum of both numbers and equating it to 18 will give;

x^2 + 3x = 18\\x^2 + 3x - 18 =0

Factorize the resulting equation:

x^2+3x -18=0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x= 3 \ and \ -6

Hence the required numbers are 3 and -6
