ind the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of π (no approximations).

Answers

Step by Step Explanation:
First find the area of the circle
Area = πr^2
=3.14 x 16
50.24 cm^2
But here we need the area of the semicircle
so 50.24/2 = 25.12 cm^2

Now we find the area of the triangle
Area = 1/2bh
= 1/2 x 8 x 4
16 cm^2

The area of the shaded region = 25.12-16
= 9.12 cm^2

Hope this helps you!

Find the product of (5.2 · 10^-6) and (8 · 10^3).A) 416 · 106-4
B) 4.16 · 10^-2
C) 41.6 · 10^-3
D) 0.416 · 10^-1

Answers

Answer: B) $4.16\cdot10^(-2)$

Step-by-step explanation:

The given product : $(5.2\cdot10^(-6))\cdot (8\cdot10^3)$

First open parenthesis :

$5.2\cdot10^(-6)\cdot 8\cdot10^3$

Write decimal values together and power of 10s together.

$5.2\cdot 8\cdot10^(-6)\cdot10^3$

Using Law of exponent : $a^m\cdot a^n= a^(m+n)$

The above expression becomes.

$41.6\cdot10^(-6+3)=41.6*10^(-3)$

In scientific notation, the decimal must be placed after one digit (from left).

$41.6*10^(-3)=4.16*10*10^(-3)\n\n=4.16\cdot10^(-3+1)\n\n=4.16\cdot10^(-2)$

Hence, the correct answer is B) $4.16\cdot10^(-2)$ .

$\displaystyle\n(5.2\cdot10^(-6))*(8\cdot10^3)=\n\n=\underbrace{5.2*8}_(41.6)*\underbrace{10^(-6)*10^(3)}_(10^(-6+3))=\n\n=41.6*10^(-6+3)=\boxed{\bf41.6*10^(-3)}\n\n\texttt{Correct answer:}~~\boxed{\bf C)}$
