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
The first question is the second answer
Answer:
c. y = -4x
Step-by-step explanation:
use slope formula
Answer:
6. Should be 10
8. X=120 degrees
Step-by-step explanation:
6. If you add 5+2+3, it equals 10
8. two of the sides are right angles. Together, they add up to be 180 degrees. the other angle is 60 degrees. 180 and 60 together are 240. Then, subtract from 360 since your shape is a quadrilateral. 360-240=120
76.47% of 15 is 11.47 you just multiply 76.47 x 15
