Volume of a cylinder = pi r^2 * h
Pi 7^2 * 20
Volume = 49 pi

Density = mass/ volume
2.5= mass/ 49 pi
Mass= density * volume
= 2.5*49 pi
= 245/2 pi
= 384.845...
=384.8 g to 1 dp


Answer= Volume

Determine the relationship between the two triangles and whether or not they can be proven to be congruent.​
Levart [38]

Answer:

- ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.

- If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Hi there,
Mrrafil [7]
We have 7 people which result ----> 7 * <u />2 = <u>14 legs</u>

Also, the table has <u>4 legs</u>

The number of the big cats is 7 *7 =49 (big cats)

For every big cat we have ---> 49 * 4= <u>196 legs</u>

For every big cat we have 7 small cats which means --> 49 * 7= 343 (small kittens)

The number of legs for small kittens is 343 * 4 = <u>1372 legs</u>

The number of legs is:
<u />
<u>14+4+196+1372= 1586 legs are in total</u>

Suppose a triangle has sides a, b, and c and the angle opposite the side of length a is acute what must be true?
ANTONII [103]

The true statement about the triangle is (a) b^2 + c^2 > a^2

<h3>How to determine the true inequality?</h3>

The sides are given as:

a, b and c

The angle opposite of side length a is an acute angle

The above means that:

The side a is the longest side of the triangle.

The Pythagoras theorem states that:

a^2 = b^2 + c^2

Since the triangle is not a right triangle, and the angle opposite a is acute.

Then it means that the square of a is less than the sum of squares of other sides.

This gives

a^2 < b^2 + c^2

Rewrite as:

b^2 + c^2 > a^2

Hence, the true statement about the triangle is (a) b^2 + c^2 > a^2
