To find out the average score, all we need to do is to add all the scores and then divide the result by the amount of numbers we added. So in this situation it'll look like this:
(10.2 + 11.4 + 10.5 + 12.6 + 12.2 + 11.6 + 13.1 + 12.8) ÷ 8 =
= 94.4 ÷ 8 =
= 11.8
Answer: Marvin's average score was 11.8.
42857 approximate hours. which will be 117 years. whoo!
1.23+0.9= 2.13
<span>2.13-1.05= 1.08
Happy studying ^_^</span>
Answer:
1)
Volume of pyramid = 1/3(Ab)(h)
Where Ab is the area of base, h is height
Volume of cone = 1/3(Ab)(h)
a) Their formula for finding volume is same. Also, their painting heads are same.
b) Pyramids have a tetragonal base while cones have a polygonal base
2) Pyramids
Volume of cone = (1/3) πr²h
Since Area of a circle = πr²
So
Volume of pyramid = (1/3)(A)(h)
So we can use the formula of a circle in cone's formula
