<u>Answer-</u>
<u>Solution-</u>
The dimensions of the cuboid is, 80×80×140 cm
So, its volume will be 
cm³
The dimensions of the cylinder is, radius = 40cm, height = 70cm
So, its volume will be 
cm³
Total volume,
As we know,
Answer:
17
Step-by-step explanation:
4w = w + 51
3w = 51

If there were 1200 people, and 65 percent were women, that means the rest of the crowd are men, which is 35 percent. By multiplying 35 percent by the overall population, 1200, (1200*35/100), you'll get 420 men.
Answer:
A. It has reflectional symmetry
B. It is symmetrical
D. It has five lines of symmetry
Step-by-step explanation:
we know that
A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides
Every regular polygon has reflectional symmetry
Regular polygons are symmetrical
therefore
A. It has reflectional symmetry ------> Is true
B. It is symmetrical -----> Is true
C. It has exactly one line of symmetry ----> Is false
D. It has five lines of symmetry -----> Is true
