Answer:
62°
Step-by-step explanation:
There should be 180° in a straight line.
63+55=118.
180-118=62
My deepest apologies if it is incorrect.
Answer:

Step-by-step explanation:
height is equal to one third times pi times radius squared times volume
Answer:
length of chord is 6cm
Step-by-step explanation:
Here, we are to calculate the length of the chord.
It should be understood that the chord has a length of 0.8cm from the center of the circle of radius 3cm, thereby forming two right-angled triangles with the radius 3cm being the hypotenuse of each and 0.8cm being the height of each.
Now, the chord is divided into 2 by this height dropping from the center of the circle. To calculate the first half, we use Pythagoras’ theorem with 3cm being hypotenuse and 0.8cm being the other side.
mathematically;
3^2 = 0.8^2 + l^2
9 = 0.64 + l^2
l^2 = 9-0.64
l^2 = 8.36
l = √(8.36)
l = 2.89 approximately
The length of the chord would be 2l = 2 * 2.89 = 5.78 cm which is 6cm to the nearest length
{<em>q</em>, <em>r</em>, <em>s</em>} consists of 3 elements, so there are 2³ = 8 possible subsets.
• empty set: { }
• every possible singleton set: {<em>q</em>}, {<em>r</em>}, {<em>s</em>}
• every possible pair: {<em>q</em>, <em>r</em>}, {<em>q</em>, <em>s</em>}, {<em>r</em>, <em>s</em>}
• the set itself: {<em>q</em>, <em>r</em>, <em>s</em>}
The volume of a cube is side^3
Volume = 11^3
Volume = 1,331 cm^3
