Answer:

54.94 inches

Step-by-step explanation:

First you need to find the radius of the semi-circles within the square.

You find this by dividing the perimeter by 8

64/8 = 8

now use the formula πr^2 to find the area of the semi circle

π8^2 = 201.06

Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region

16*16 = 256

256-201.06 = 54.94

Answer:

c) ( $(6-\sqrt{12} )(6+\sqrt{12} ) = 24$

d) ( $(3+\sqrt{8} )(3-\sqrt{8} ) = 1$

Step-by-step explanation:

Step(i):-

Given that the binomial expression

( $(6-\sqrt{12} )(6+\sqrt{12} )$

Multiply

( 36 + 6√12 -6√12 -(√12)²)

= ( 36 -12)

= 24

c) ( $(6-\sqrt{12} )(6+\sqrt{12} ) = 24$

Step(ii):-

Given that the binomial expression

( $(3+\sqrt{8} )(3-\sqrt{8} )$

Multiply

= 9 - 3√8 + 3√8 -(√8)²

= 9 - 8

= 1

d) ( $(3+\sqrt{8} )(3-\sqrt{8} ) = 1$

PELASE HELP ME QUICK?!!!!!!!!

labwork [276]

Answer:

The correct answer is $2.32*10^6$ . The exponent $10^4$ is wrong since the decimal place was moved six from the right. Additionally, the exponent number isn't dependent on the amount of zeros, but the amount of times the decimal place was moved.

Step-by-step explanation:

Each place you move the decimal, you have to add or subtract one to the exponent.

If you move the decimal place towards the left, you add one.

If you move the decimal place toward the right, you subtract one.

The exponent number isn't dependent on the amount of zeros, but the amount of times you moved the decimal place. To get from 2,320,000 you must move the decimal place 6 times to the left to get 2.32. Hopes this helps!
