Answer:

28.26 square feet

Step-by-step explanation:

Area of a circle is: $A=\pi r^2$

'r' is the radius.

We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.

6/2 = 3

Using 3.14 for pi:

$A=3.14*3^2\\\rightarrow 3^2=9\\A=3.14*9\\\boxed{A=28.26}$

The area of the circle should be 28.26 square feet.

Answer:

28.26 ft²

Step-by-step explanation:

If the diameter is 6 feet, then the radius is 3 feet since 2r=d

The area formula in this case is 3.14×r² since it says "Use 3.14 for π".

3.14×3²=

3.14×9=

28.26 ft²

$\sqrt{-4}$ can also be written as 2i
where i = √-1

$\frac{2i}{4-2-3i} = \frac{2i}{2-3i}$

Rationalizing denominator,

$\frac{2i(2+3i)}{(2-3i)(2+3i)} = \frac{4i-6}{4+9} = \frac{4i-6}{13}$

5s-(100+2s =4s-2(10+s) how much boxes would they need to sell to get a equal amount each group must sell to have equal profits.

antoniya [11.8K]

5s-100-2s=4s-20-2s
3s-100. = 2s-20
+20. +20
3s-80. = 2s
-3s. -3s
-80. = -1s
-1 -1
80. = s

s=80
