A prism is created using 2 regular pentagons as bases. The apothem of each pentagon is 2.8 centimeters. Which expression represe

mash [69]

Recall that the volume of a regular prism is given by the area of the base times the height.

Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.

Recall that the are of a triangle is given by 1/2 base times height.

Thus the area of of the pentagon base of the prism is given by
$Area= \frac{5}{2} x\times2.8=7x$

Therefore, the volume of the prism is given by
$Volume=7x(2x+1)=14x^2+7x$

Mark the statements that are true. A. An angle that measures π/4 radians also measures 45°. B. An angle that measures 180° also

FinnZ [79.3K]

Answer:

TRUE: A, B, C

False: D

Step-by-step explanation:

A full circle of 360° has a radian measure of 2π radians. The relationship is proportional, so π radians is 180°.

__

A. An angle that measures π/4 radians also measures 45°. TRUE

45° × π/180° radians = π/4 radians

B. An angle that measures 180° also measures π radians. TRUE

180° × π/180° radians = π radians

C. An angle that measures 60° also measures π/3 radians. TRUE

60° × π/180° radians = π/3 radians

D. An angle that measures π/3 radians also measures 30°. FALSE

30° × π/180° radians = π/6 radians

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away

elixir [45]

Answer:

<u>10.1 miles</u> far is their house.

Step-by-step explanation:

Given:

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away.

Now, to find the distance is far from their house.

14.6 miles distance they ran from their house.

So, they are far from house = $14.6\ miles.$

Then, 9.8 miles they are from their house.

So, they are far from house = $14.6-9.8\ miles=4.8\ miles.$

And, finally 5.3 miles away from their house.

So, now they are far from house = $4.8+5.3=10.1\ miles.$

Therefore, 10.1 miles far is their house.
