Well, to calculate the area, we would simply do length times width and we would get our area.
Area = Length * Width
Area = 12cm * 4cm
Area = 48cm squared.
So, in conclusion, the area is 48 cm squared.
Answer:
43.3cm
Step-by-step explanation:
Circumference = PI * diameter.
Circumference = PI * 13.8
Circumference = 43.3cm
<span>If c = 30 and d = 8, then
2c + 4d
= 2(30) + 4(8)
= 60 + 32
= 92</span>
Answer:
80
Step-by-step explanation:
So assuming that each thing is 1.6:3 smaller
radius=1.6r to radius=3r
height=1.6h to height=3h
volume=pi times r^2 times height
1.6 3
pi times (1.6r)^2 times 1.6h to pi times (3r)^2 times 3h
pi times 2.56r^2 times 1.6h to pi times 9r^2 times 3h
pi times 4.096hr^2 to pi times 27hr^2
so the ratio is
pi times 4.096hr^2:pi times 27hr^2
divide both sides by pi
4.096hr^2:27hr^2
divide both sides by hr^2
4.096:27
answer is 4.096/27
