Answer:
Step-by-step explanation:
11 and 12
Volume of sphere is
V=4/3pi r^3
Where r is 2 in this example so,
V= 10.67 pi
V= 33.51
<h3>
Answer: 100 meters</h3>
===========================================
Explanation:
If you draw out the diagram, then you'll find that a 45-45-90 triangle forms. The nice thing about this type of triangle is that the two legs are always the same length. The horizontal leg is 100 meters, so the vertical leg must also be 100 meters.
Side note: this type of triangle is an isosceles right triangle.
---------
You could use the tangent rule to get the same thing
tan(angle) = opposite/adjacent
tan(45) = 100/x
1 = 100/x
1*x = 100
x = 100
In this case, the opposite leg is the vertical leg since it is furthest from the angle of elevation.
Answer:
£682.57
Step-by-step explanation:
Dan pays £714.73 a year in his car insurance.
The price was reduced by 4.1%
To find the new cost of the insurance, we simply need to find 4.15% of £714.73 and then subtract that from the initial price of the insurance (£714.73)
4.5% of 714.73 is:
= £32.16
Then, the cost of the insurance now is:
£714.73 - £32.16 = £682.57
The insurance now costs £682.57
