Answer:

2.01  \: {inches}^{2}

The formula to find the area of a circle is

area \: of \: circle \:  = \pi {r}^{2}

Let pi be (3.14), the radios as given in the question is (1.6 ÷ 2 = 0.8). Therefore;

\pi {r}^{2}  =  \\ (3.14) \: {(0.8)}^{2}  \\ 3.14 \times 0.64 =  \\ 2.0096\: or \: 2.01{inches}^{2}

RoseWind [281]

From figure 1: -

From figure 2: 12

From figure 3: 6

From figure 4: -12

From figure 5: -2

Step-by-step explanation:

We need to solve the equation 4k-6=-2k-16-2 for k.

Solving:

4k-6=-2k-16-2\\4k-6=-2k-18\\4k=-2k-18+6\\4k=-2k-12\\4k+2k=-12\\6k=-12\\k=\frac{-12}{6}\\k=-2

So, the options to be selected are:

From figure 1: -

From figure 2: 12

From figure 3: 6

From figure 4: -12

From figure 5: -2

Is this the correct answer?
Step2247 [10]

Step-by-step explanation:

Close.  You correctly set up the integrals.  When integrating e²ˣ:

∫ e²ˣ dx

½ ∫ 2 e²ˣ dx

½ e²ˣ + C

So the coefficient should be ½, not 2.

[eˣ − ½ e²ˣ]₋₁⁰ + [½ e²ˣ − eˣ]₀¹

[(e⁰ − ½ e⁰) − (e⁻¹ − ½ e⁻²)] + [(½ e² − e) − (½ e⁰ − e⁰)]

1 − ½ − e⁻¹ + ½ e⁻² + ½ e² − e − ½ + 1

-e⁻¹ + ½ e⁻² + ½ e² − e  + 1
