The area of a circle is <u>(pi) x (the circle's radius)</u>²
The circle's radius is (1/2) of (its diameter).
Area = (pi) x (12/2 inches)² =
(pi) x (6 inches)² =
(3.14) x (36 square inches) = <em>113 square inches</em> (rounded)
Use the distributive property.
4(4a + 5) = 4 * 4a + 4 * 5 = 16a + 20
Answer: 16a + 20
Answer:

Step-by-step explanation:
we will solve this using integration by parts as the problem is a product of two functions which none of them are constants.
∫udv = uv -∫vdu ..............equ 1
∫
u=x ,
du= 1
dv =
v=∫dv= 
Substituting into equ 1
∫udv =
- ∫
<em>∫udv =
</em>
I think you add two more every row so there would be 13 in the 7th row
