This is simple.

=3\frac{3}{5} ÷ 4\frac{1}{2}
change the mixed fractions to improper ones.
\frac{18}{5} ÷ \frac{9}{2}
Multiply \frac{18}{5} by the reciprocal of \frac{9}{2} which is \frac{2}{9}  
 
=\frac{18}{5} ×  \frac{2}{9}
=\frac{36}{45}

Since it can be simplified further, we get the answer
\frac{4}{5}

How?
There is a common multiple 9
\frac{36/9}{45/9}
=\frac{4}{5}
Answer= B. \frac{4}{5}

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a height of 10 meters and a circular base wi
nirvana33 [79]

Answer: Volume of an oblique cylinder is 2011.43 sq.m.

Step-by-step explanation:

Since we have given that

Radius of a cylinder = 8 meters

Height of a cylinder = 10 meters

Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.

As we know the formula for "Volume of cylinder":

Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43

Hence, Volume of an oblique cylinder is 2011.43 sq.m.

Explain why segments connecting any pair of corresponding vertices of congruent pentagons are congruent. make a sketch to suppor
Veronika [31]

Answer:

Congruence between pentagons

Step-by-step explanation:

The relationship occurs because having two congruent Pentagons and generating a segment within them (or outside), congruence is extrapolated to the triangles generated within them. Thus, if there is congruence among the pentagons, it will exist between the formed triangles. In other words since the two pentagons are congruent, the corresponding angle pair is congruent. also the two corresponding side pairs are also congruent.

In the attached image for example, the ABCDE and KLMNO pentagons are congruent, so all of their internal division lines are also congruent (AC and KM)
