Answer:
64 m³
Step-by-step explanation:
For similar figures
linear ratio = a : b , then
area ratio = a² : b² and
volume ratio = a³ : b³
Given
area ratio = 64 : 144 , then
linear ratio =
:
= 8 : 12 = 2 : 3
Then
volume ratio = 2³ : 3³ = 8 : 27
let volume of smaller cylinder be x, then
=
( cross- multiply )
27x = 8 × 216 = 1728 ( divide both sides by 27 )
x = 64
Volume of the smaller cylinder = 64 m³
Answer:
294.5 m²
Step-by-step explanation:
shaded region = area of major sector + area of triangle
central angle of major sector = 360° - 130° = 230°
area of sector = area of circle × fraction of circle
A = π × 11.1² × ![\frac{230}{360}](https://tex.z-dn.net/?f=%5Cfrac%7B230%7D%7B360%7D)
=
≈ 247.3 m²
area of triangle = 0.5 × 11.1 × 11.1 × sin130° ≈ 47.2 m²
shaded area = 247.3 + 47.2 ≈ 294.5 m²
0.008 km to m
To convert from km to m:
Formula: multiply the value in kilometers by the conversion factor ‘1000’
Do 0.008 km = 0.0008 * 1000 = 8 meters
Answer:
-|12|
Step-by-step explanation:
|19| is 19, -|19| is -19
|12| is 12, -|12| is -12
-12>-19
