This figure is made up of a quadrilateral and a semicircle.
Arturiano [62]

Answer:

The correct option is B. The area of the figure is 40.4 units².

Step-by-step explanation:

The line AB divides the figure in two parts one is a rectangle and another is semicircle.

The distance formula is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of AB is

AB=\sqrt{(2+3)^2+(4-2)^2}=\sqrt{25+4}=\sqrt{29}

The length of AD is

AD=\sqrt{(-1+3)^2+(-3-2)^2}=\sqrt{4+25}=\sqrt{29}

Since AB=AD, therefore ABCD is a square. The area of the of square is

A_1=a\times a=\sqrt{29}\times \sqrt{29} =29

The area of square is 29 units².

The area of a semicircle is

A_2=\frac{\pi}{2}r^2

Since AB is the diameter of the semicircle, therefore the radius of the semicircle is

r=\frac{d}{2}=\frac{\sqrt{29}}{2}

The area of the semicircle is

A_2=\frac{3.14}{2}(\frac{\sqrt{29}}{2})^2=40.3825

The area of the figure is

A=A_1+A_2=29+11.2825=40.3825\approx 40.4

Therefore the area of the figure is 40.4 units². Option B is correct.

What is the cube root of 27a12
satela [25.4K]

Answer:

3a^4

Step-by-step explanation:

Given expression is 27a^{12}.

Now we need to find the cube root of given expression 27a^{12}.

\sqrt[3]{27a^{12}}

=\sqrt[3]{3*3*3a^{4*3}}

=\sqrt[3]{3^3\left(a^4\right)^3}

=\sqrt[3]{\left(3a^4\right)^3}

Since cube root and cube are opposite operations of each other. So they will cancel each other.

=3a^4

Hence correct choice is the last choice 3a^4.
