The following figure is made of six semicircles with the same diameter, and of four congruent equilateral triangles represented
Oxana [17]

6 semicircles = 3 circles

The formula of the area of a equilateral triangle:

A_\triangle=\dfrac{a^2\sqrt3}{4}

We have a = |AE| = 3cm. Substitute:

A_\triangle=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\ cm^2

The formula of the area of a circle:

A_O=\pi r^2

We have 2r = |AE| =3cm → r = 1.5cm. Substitute:

A_O=\pi\cdot1.5^2=2.25\pi\ cm^2

The area of the figure:

A=4A_\triangle+3A_O\\\\A=4\cdot\dfrac{9\sqrt3}{4}+3\cdot2.25\pi=9\sqrt3+6.75\pi=6\dfrac{3}{4}\pi+9\sqrt3\\\\=\dfrac{27}{4}\pi+\dfrac{36\sqrt3}{4}=\dfrac{9}{4}\cdot3\pi+\dfrac{9}{4}\cdot4\sqrt3=\dfrac{9}{4}(3\pi+4\sqrt3)\ cm^2

I need to know the answer
ladessa [460]

Answer:

b

Step-by-step explanation:

Answer: option (b)

1 billion = 1, 000, 000, 000

In scientific notation, a number is rewritten as a simple decimal multiplied by 10 raised to some power n.

10 =101

100= 102

1, 000 = 103

1, 0000 = 104.

..............

Therfore 1 billion can be written as

1 billion =1, 000, 000, 000=10^{9}

Then 1.5 billion =  1.54 10^{9}

Hence option (b) is the correct answer

please give me brilliant answer

thank you
