Answer:

12.56 cm

Step-by-step explanation:

Area of a circle is A=3.14 r to the second power.

so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56

Answer:

12

Step-by-step explanation:

The formula to find the area of a circle is:

\pir^{2}

Where "r" is the radius of the circle.

In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.

The equation will be:

3 * 2^2

Simplify, remember the order of operations:

3 * 4

The numerator of a fraction is 3 less then the denominator. If 1 is added to the numerator, the value of the fraction becomes 3/
andrew11 [14]

The fraction is \frac{5}{8}

Step-by-step explanation:

Let,

The denominator of fraction = x

Numerator of fraction = x-3

Fraction = \frac{x-3}{x}

According to given statement;

1 is added to the numerator, the value of the fraction becomes 3/4.

\frac{x-3+1}{x}=\frac{3}{4}\\\\\frac{x-2}{x}=\frac{3}{4}

Using cross multiplication

4(x-2)=3*x\\4x-8=3x\\4x-3x=8\\x=8

Fraction = \frac{x-3}{x}=\frac{8-3}{8}=\frac{5}{8}
