Answer:
66.28 sq. km
Step-by-step explanation:
the area of fig. =
(4×3)+(8×6)+(½×3.14×2²)
= 12+48+6.28
= 66.28 sq. km
1 1/2 feet can be written as 1.5 feet and 20 years * 1.5 feet per year = 30 feet. Assuming the maple tree started at 0 feet, it will be 30 feet tall in 20 years.
200 beads = $48, so 48÷200 = $0.24, which is the cost of one bead.
If the cost of 1 bead is $0.24, then 25×0.24 = $6
25 beads cost $6
Answer:
Volume = 3.15 cm³
Step-by-step explanation:
mass = 5 gram
density = 1.59 g/cm³
now
density = mass/ volume
or, 1.59 = 5/v
or, v = 5/1.59
so, v = 3.15 cm³
