I need help find the volume of the composite solid use 3.14 for pi

Mathematics
1 answer:
Evgen [1.6K]3 years ago
5 0

Answer:

222.312\:\mathrm{in^3}

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: \frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912

Volume of the cylinder: 2^2\cdot 3.14 \cdot 15=188.4

Thus, the total volume of the solid is:

33.912+188.4=\boxed{222.312\:\mathrm{in^3}}

Use the compound interest formulas A = Pert and A = P(1 + ) to solve. Suppose that you have $11,000 to invest. Which investment
gulaghasi [49]

Answer:

Continuously

Step-by-step explanation:

Compounded continuously:

A = Pe^(rt)

A = 11,000 e^(0.0625 × 10)

A = 20,550.71

Compounded semiannually (twice per year):

A = P(1 + r)^t

A = 11,000 (1 + 0.063/2)^(2×10)

A = 11,000 (1 + 0.0315)^20

A = 20,453.96

Evaluate 19C1 PLEASE HELP
LiRa [457]

Answer:

{19}C_1=19

Step-by-step explanation:

We need to find the value of {19}C_1.

C stands for combination.

The formula of combination is as follows :

nC_r=\dfrac{n!}{r!(n-r)!}

Here,

n = 19 and r = 1

So,

nC_r=\dfrac{19!}{1!(19-1)!}\\\\nC_r=\dfrac{19!}{1!\times 18!}\\\\nC_r=\dfrac{19\times 18!}{1!\times 18!}\\\\nC_r=19

So, the value of {19}C_1 is 19.

In Walmart parking, there are 175 vehicles parked joe figures out that 64% of the vehicles are white. How many vehicles are NOT
aksik [14]

Answer:

63 vehicles are not white

Step-by-step explanation:

Well you know that there are 175 total vehicles, and that 64% of those vehicles are white.  Therefore the remaining percentage of vehicles must not be white.

100%-64%=36%

This means that 36% of the vehicles aren't white.

Now you must find what 36% of 175 is.  The word "of" always signals for multiplication, which is exactly what you need to do here.  First start by converting the percentage into decimal form:

36%=0.36

Now you can multiply

175 x 0.36 = 63

63 Vehicles are not white

Elden [556K]
The first step to take is to plot the coordinates of the figure. Next, we caculate the distances of the sides of the polygon using distance formula given the coordinates of points. Next we get the midpoint of each side and connect them to each other. we calculate again the distances. The resulting figure is composed of four congruent sides but the angles are not perpendicular. The answer is D. rhombus
