First find the volume of the cylinder.

The formula is: V=πr²h

Plug the numbers in the figure into the formula.

V=πr²h

V=π×3²×10

V=π×9×10

V=π90

V=282.743

Therefore, the volume of the cylinder is approximately 282.7in³

Find the volume of the rectangluar prism.

V=lwh

V=12×7×4

V=84×4

V=336

Therefore, the volume of the rectangular prism is 336in³

Add the volumes:

282.7+336=618.7

The volume of the composite solid is approximately 618.7in^3

In an automobile parts factory, for every 175 carburetors 3 are found to be defective. At that rate how many carbureatots out of

Furkat [3]

Answer:

At the same rate 18 carburetors out of 1,050 could be expected to be detective.

Step-by-step explanation:

The number of carburetors tested = 175

Defective pieces out o f 175 = 3

So, ratio of defected to tested = 3 : 175

Now, the number of carburetors tested in second batch = 1,050

Here, let the defective pieces = m

So, by the Ratio of Proportion,

$\frac{3}{175} = \frac{m}{1050}$

or, $m = \frac{1050 \times 3}{175} = 18$

⇒ m = 18

Hence, at the same rate 18 carburetors out of 1,050 could be expected to be detective.

If 6 sandwich rolls cost $1.44, how much will 26 rolls cost?

tresset_1 [31]

$6.24. This is because 1.44 / 6 = 0.24, and 0.24 x 26 = 6.24.

Answer:

Vertical angles

Step-by-step explanation:

: If two angles are vertical angles, then they're congruent (see the above figure). Vertical angles are one of the most frequently used things in proofs and other types of geometry problems, and they're one of the easiest things to spot in a diagram. Don't neglect to check for them!

Angle $eab$ is a right angle, and $be = 9$ units. what is the number of square units in the sum of the areas of the two squares

Alla [95]

Let the measure of side AB be x, then, the measue of side AE is given by

$AE=\sqrt{9^2-x^2}$ .

Now, ABCD is a square of size x, thus the area of square ABCD is given by

$Area=x^2$

Also, AEFG is a square of size $\sqrt{9^2-x^2}$ , thus, the area of square AEFG is given by

$Area=\left(\sqrt{9^2-x^2}\right)^2=9^2-x^2=81-x^2$

The sum of the areas of the two squares ABCD and AEFG is given by

$x^2+81-x^2=81$

Therefore, the number of square units in the sum of the areas of the two squares ABCD and AEFG is 81 square units.
