Answer: 8.37 in³
Step-by-step explanation:
Given the following :
Shape of icre cream scoop = sphere
Radius (r) = 1 inch
Volume of a scoop of icecream = volume of sphere :
4/3πr³
(4/3) × 3.14 × 1³
1.333 × 3.14 × 1
= 4.1867 in³
Hence, the volume of 2 scoops of ice cream will be :
2 × ( volume of a scoop of ice cream)
(2 × 4.1867) in³
= 8.37 in³
Answer:
40:80
Step-by-step explanation:
x+2x=3x
3x=120
120/3=
40
40*2=80
40:80=1:2
Answer: It's about 10.34%
Step-by-step explanation:
Given:
12 rectangular planks
2 sides per plank
Length = 8 ft
Width = 3 ft
Area of a rectangle = Length * Width.
A = 8ft * 3ft
A = 24 ft²
24 ft² x 2 sides of a plank = 48 ft²
48 ft²/plank * 12 planks = 576 ft² is the total area Alex needs to varnish.
576 ft² ÷ 125 ft² = 4.608 pint or round to 5 pints
5 pints x $3.50/pint = $17.50 Total cost that Alex need to spend to varnish all the wooden planks.
The ratio is 8:20
