Answer:

2√3

Step-by-step explanation:

Be sure you don't answer √(12) even though the brackets make clear what you mean.

12 factors into 2*2*3

Rule: for ever 2 factors that are the same under a root sign, you can take out 1 of them and throw the other one away.

√(12) = √(2 * 2 * 3) = 2√3.

Notice that the 2 is part of the answer.

A circle has an equation (x+2)2+(y−5)2=64. What is 34 of its area.
skad [1K]

Answer:

3/4 of the area of the circle is of 48\pi squared units.

Step-by-step explanation:

Equation of a circle:

The equation of a circle has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

In which the center is (x_0,y_0) and r is the radius.

Area of a circle:

The area of a circle of radius r is given by:

A = \pi r^2

Circle (x+2)² + (y-5)² = 64

Comparing with the standard equation, we have that:

r^2 = 64

Area of the circle:

A = \pi r^2 = 64\pi

What is 3/4 of its area?

\frac{3A}{4} = \frac{3*64\pi}{4} = 3*16\pi = 48\pi

3/4 of the area of the circle is of 48\pi squared units.
