Answer:
this is just for part A sorry i dont get part B
oof bad drawing of a trapezoid
Answer:
- cylinder — 90π in³
- pyramid — 37 1/3 in³
- cone — 12.5π in³
Step-by-step explanation:
The volume of a cylinder is given by ...
V = Bh . . . . . where B is the base area and h is the height
The volume of a pyramid or cone is given by ...
V = (1/3)Bh . . . . . where B is the base area and h is the height
The area of a square of side length s is ...
A = s²
The area of a circle of radius r is ...
A = πr²
___
Using these formulas, the volumes of these objects are ...
cylinder: (9π in²)(10 in) = 90π in³
square pyramid: (1/3)(4 in)²(7 in) = 37 1/3 in³
cone: (1/3)(π(2.5 in)²)(6 in) = 12.5π in³ . . . . slightly larger than the pyramid
Answer:
down ⬇⬇⬇
Step-by-step explanation:
5. its all of them so just write A, B, C, D, E, F, G
6. (equilateral) triangle, right triangle, diamond (?), parallelogram
7. C and E; A and B
8. not so sure about this one but i think its regular
9. its not a polygon because polygons have straight sides, and this figure does not.
10. the only polygon is C
pay attention in school, it'll help in the long run. even if it sounds boring, it will come in handy one day!!
