Find the area of the figure ​

Mathematics
1 answer:
Kay [80]2 years ago
8 0

Answer:

26.13 ft^2

Step-by-step explanation:

The area of the triangle is (1/2)(height)(base) = (1/2)(4)(6) = 12.  (The base is 6 because it is made up of two radii of the semicircle.)

The area of a whole circle is pi(radius)^2.

Area of whole circle is pi(3^2) = 9pi.  But you have only half a circle, so its area is 4.5pi.

Using 3.14 to approximate pi, the area of the semicircle is 4.5(3.14) = 14.13.

Adding this to the area of the triangle, you get a total area

14.13 + 12 = 26.13 ft^2

Find the difference of(ab+8a+1)-(-6ab+4)
vagabundo [1.1K]
Hey there!

When finding the difference of expressions like these, there's a few things you should keep in mind. 

1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve. 

2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them. 

3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses. 

With all that in mind, you can go ahead and solve for your difference, like so:

(ab+8a+1)-(-6ab+4)

(ab+8a+1) (-1(-6ab+4))

(ab+8a+1) + (6ab-4)

ab+6ab+8a+1-4

7ab+8a-3

7ab+8a-3 will be your difference. 

Hope this helped you out! :-)
