Answer:

<u>The correct answer is D. 414 in squared.</u>

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Area of the first circle = 11.5 inches ²

2. Let's calculate the area of the new circle, given that the radius of the first circle is multiplied by 6.

Area of the first circle = 11.5 inches ²

Let's find the radius:

π * r² = 11.5

r² = 11.5 / 3.1416

r² = 3.66055513

r = 1.91 inches

The first circle has a radius of 1.91 inches

So, the radius of the second circle is 1.91 * 6 = 11.48 inches

Area of the second circle = π * r²

Area of the second circle = 3.1416 * 11.48²

Area of the second circle = 3.1416 * 131.79

Area of the second circle = 414.03 inches ²

<u>Area of the second circle = 414 inches ² (Rounded to the nearest whole number)</u>

<u>The correct answer is D. 414 in squared.</u>

Answer:

0.333\pi units³

Step-by-step explanation:

Think process:

The equation is given as y = e^{-3x}

Let, y = f (x)

Therefore, f (x) = e^{-3x}

We know that the limits are y-axis and x= 3

Y-axis: x= 0

then limits are given as x= 0 and x = 3

Integrating  gives:

\int\limits^3_0 {e^{-3x} } \, dx = \frac{-1}{3}e^{-3x} + C

calculating from x= 0 to x = 3, we know volume is given by \pi \int\limits^a_b {f(x)} \, dx

= \pi[ \frac{-1}{3} e^{-9}  - (\frac{-1}{3} e^{0})]

= \pi[0.000041136 + 1/3]

= 0.333\pi units³

Vadim26 [7]
The experimental probability is computed to be 43/150 or approximately 28.67%. This is computed by dividing the event of number 3 showing by the total number of times the cube is rolled.
The theoretical probability is computed to be 1/6 or approximately 16.67%. Since there is only one side with the number 3, and there is a total of six sides in a cube. Theoretical probability assumes that the number cube is fair and all sides have equal chances of showing up.
