Answer:

80π

Step-by-step explanation:

Circle O with radius IO:

large radius = IO = 12 = R

Circle O with diameter JK

IJ = JK = KL = 2 × IO = 24

IJ = JK = KL = 24/3 = 8

small radius = 8/2 = 4 = r

The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.

That is the same as

1 semicircle of radius 12 plus 1 semicircle of radius 4

A = πR²/2 + πr²/2

A = π(12² + 4²)/2

A = 160π/2

A = 80π

kari74 [83]

Answer:

Step-by-step explanation:

1.) Apply the distributive law

5x + 5 * 2

2.) Multiply the numbers

5 * 2 = 10 is equivalent to 5x + 10

3.) Group like terms

5x - 3 + 10

4.) Add/subtract the numbers

-3 + 10 = 7 is equivalent to 5x + 7

5+-4*1/3 Show work pls

polet [3.4K]

To solve this, we need to follow PEMDAS (Order of Operations)

P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction

Following this order of math will get you your answer for any math problem.

First we'll do -4*1/3, which gets us -4/3. Then we'll add 5 to get $3 \frac{2}{3}$
