Immediately omit the negative possible answer. Since 5^2 = 25, 1/5^2 = 1/25.

Below is the justification for the formula for area of a circle. Which word, when placed in the blank best completes this argume

mote1985 [20]

Answer:

The correct answer is option A. r

Step-by-step explanation:

From the figure we can see a circle and a parallelogram.

The circle is divided into a small sectors and these sector then arranged into a parallelogram.

The base of the parallelogram is half the circumference.

The height of parallelogram is equal to the radius of the given circle. Here radius is 'r'.

Therefore the correct answer is option A. r

ASAP please help I’m failing math

MariettaO [177]

Answer:

Part A) The volume of the entire cone is $168\pi\ in^3$

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values

$\frac{7}{14}=\frac{3}{x}$

solve for x

$x=14(3)/7\\x=6\ in$

To find out the volume of the entire cone we have

$r=CE=x=6\ in$

$h=AC=14\ in$

substitute in the formula

$V=\frac{1}{3}\pi (6)^{2}(14)$

$V=168\pi\ in^3$

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values and solve for x
