Diameter = 21 ft
Radius = 21/2 ft

Area of a semi circle = πr^2 /2

= 3.14 x( 21/2 )^2/2
= 346.185/2
= 173.0925 ft^2

The answer is 173 ft^2

We know, Area of a Semi-circle = πr² / 2
Here, r = 21/2 = 10.5

So, A = 3.14 * (10.5)² / 2
A = 346.185 / 2
A = 173.09 Ft²

In short, Your Answer would be 173 Feet²

Hope this helps!

Its non of the above. Though I did have a question like that, if there is a choice below the square, that has the following properties, that must be the answer:

7 sides

1 right angel

______________________________________________________

But if you are talking about it being 1 of the 2, its non of the 2 that is in the picture. The option below square must be the answer if I am right according to what I had.

Hope it helps ! The things that I told you about the figure is the only way I can tell you. Sorry, but have a great day and good luck.

I need it within tomorrow please
Alenkinab [10]

Any even number raised to any power will remain even. (e.g. 2² = 4, 2³ = 8, etc)

Any odd number raised to any power will remain odd. (e.g. 1² = 1³ = ... = 1, 3⁴ = 81, etc)

So (n+1)^{2^k}-n^{2^k} will always be even, since both

[even] - [odd] = [odd]

and

[odd] - [even] = [odd]

= -4.5(-22.1)

= 99.45


4.5 * 22.1 
= 99.45


-45 * 2.21

= -99.45

= -99


Therefore, your answer is:

Option C.


Good luck on your assignment & enjoy your day!
