Answer:

The best estimate of he area of the figure is 38.28\ cm^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a semicircle plus the area of rectangle plus the area of a right triangle

so

A=\frac{1}{2}\pi r^{2}+LW+\frac{1}{2}bh

we have

<em>Semicircle</em>

r=4/2=2\ cm ----> the radius is half the diameter

\pi=3.14

<em>Rectangle</em>

L=6\ cm

W=4\ cm

<em>Triangle</em>

b=10-6=4\ cm

h=4\ cm

substitute the values

A=\frac{1}{2}(3.14)(2)^{2}+(6)(4)+\frac{1}{2}(4)(4)

A=6.28+24+8=38.28\ cm^{2}

Half of a number increased by 4 is 30.
Hitman42 [59]

Answer:

\frac{1}{2}x+4=30

52

Step-by-step explanation:

First, write the equation out in the algebraic form. Half of a number is equivalent to a number times 1/2. Additionally, increasing a number by 4 is just adding 4. So the equation is \frac{1}{2}x+4=30.

Then, use algebra to solve.

1) Subtract 4 from both sides

1/2x=26

2) Multiply both sides by 2, because that is the same as dividing by a fraction

x=52
