The answer is 4. V= pi r^2 h. Square the radius first and multiply it by the height. That gives you 1.125, then multiply by 3.14 because that’s what you’re using for pi. You’ll end up getting 3.54. Round to the nearest whole number and you get 4.

Evaluate the following integral over the specified region. Assume (r comma theta )(r,θ) are polar coordinates. ModifyingBelow In
topjm [15]

Answer:

Step-by-step explanation:

We have to integrate the function

16+x^2+y^2 over the region

1\leq r\leq 3\\0\leq \theta \leq \pi

Let us convert into polar coordinates

x=cost : y = sint

Then we get dxdy = rdr dt

So we get the integral as

\int \int _R (16+x^2+y^2)^2 dxdy\\= \int\limits^3_0 \int\limits^\pi_0( {16+r^2}^2) (r)drdt\\ =(t) (\frac{(16+r^2)^3}{6}

Substitute the limits to get

Answer

=(\pi-0) [\frac{1}{6} (25-16)\\=1.5 \pi

Divide and simplify 3/4÷2/3
Ne4ueva [31]
To start off, you have to change 2/3 into 3/2 and then multiply it by 3/4. (Which the equation becomes into 3/4 × 3/2.) Then solve 3/4 × 3/2 =9/8 or 1 and 1/8.

Question 5 pleaseeee
vovikov84 [41]

Answer:

first

Step-by-step explanation:

f(n) =56 (0.5)^(n-1)

f(1) = 56 (0.5)^0= 56*1 = 56

f(2) =56 (0.5)^1 = 56* 0.5 = 28

f(3) = 56 (0.5)^2 = 14

f(4) = 56 (0.5)^3 = 7
