Answer:
i) 60°
ii) 14.7 cm
Step-by-step explanation:
length of Arc BA = 8.4 cm
length of radius = 8 cm
angle AOC = 45°
BO = AO = CO = 8 cm
<u>i) What is the measure of Angle BOA </u>
= length of Arc BA / Radius
= 8.4 / 8 = 1.05 radians = 60.16° ≈ 60°
<u>ii) what is the length of arc BAC</u>
= radius * angle BAC *
angle BAC = angle AOC + angle BOA
= 45° + 60° = 105°
hence length of arc BAC
= 8 * 105 *
≈ 14.7 cm
Answer: Volume of sugar cube=2.20 cm³
Density of sugar cube = 1.60 g/cm³.
The sugar cube will sink.
Step-by-step explanation:
Given : Mass of cube = 3.48 g
Also, dimension of sugar cube :
height = length = width = 1.3 cm
Since , the volume of cube = (side)³
Volume of sugar cube=(1.3) ³= 2.197 ≈ 2.20 cm³
Also, Density =
⇒ Density of sugar cube =
∴ Density of sugar cube = 1.60 g/cm³.
It is known that the density of water is 1 g/cm³.
Here , density of sugar cube > density of water
⇒ The sugar cube will sink .
