#7 is kind of hard to read
Answer:
Step-by-step explanation:
v=4pi*r^3/3=3052.08
4*3.14/3*r^3=3052.08
4.2*r^3=3052.08
r^3=3052.08/4.2=726.7
so r ≈9
Answer:
0.4896
Step-by-step explanation:
just use a calculator ahaha
Given:
Composite figure
To find:
The shapes in the composite figure.
Solution:
The image splitted into three shapes.
- Draw a line from top vertex to bottom vertex.
- We get one triangle.
- Similarly, draw another line adjacent to the previous line.
- We get another triangle and rectangle.
Therefore a composite figure divided into a rectangle and two triangles.
Answer:
Simplify the problems first
Step-by-step explanation:
Before you can convert it to scientific notation, you should simplify it first.
#1 for example:

Use PEMDAS to solve the equation:

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be
since there are 11 places after the decimal.
