Answer:
The correct answer is 63 cubic inches.
Step-by-step explanation:
Dali rolled up his painting and placed it in a cylinder 2 inches diameter.
Diameter of the painting is 2 inches. This also implies diameter of the cylinder is 2 inches.
Radius of the cylinder is 1 inch.
Length of the cylinder is 20 inches.
Volume of the cylinder is given by π × × h = π × × 20 = 20π = 62.85 cubic inches ≈ 63 cubic inches.
Therefore the volume of the cylinder in which Dali placed his painting is given by 63 cubic inches.
Answer:
h = 19 mm
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height )
the base is a regular pentagon whose area (A) is calculated as
A = pa ( p is the perimeter and a the apothem )
p = 5 × 12 = 60 mm and a = 5 mm , then
A = × 60 × 5 = 30 × 5 = 150 mm²
given V = 2850 , then
150h = 2850 ( divide both sides by 150 )
h = 19 mm
Answer:
B. first step
6/7x=7/8-1/2
c. second step
6/7x=7/8-4/8=3/8
d. and e are the same
x=3/8x7/6
Step-by-step explanation:
Answer:
Jersey: 85.75/100 X 80 = $68.60
Tennis Racket 55% = 49.05, 1%=0.89181818, 100% = 89.1818181 = $89.18
Archery = 94- 61.10 = 32.90, 32.90/94= 0.35
0.35 X 100 = 35%
