Answer:
Area = 23.38 square"
Step-by-step explanation:
It is given that a regular hexagon is having a side = 3"
Since hexagon is inscribed in a circle therefore all the triangles formed by the radii and the sides of hexagon will be equilateral triangles.
In a hexagon number of triangles formed = 6
Area of an equilateral triangle = 1/4s²√3
By putting the value of s = 3"
Area of one triangle = 1/4×3²√3 = (9√3)/4
and we know number of triangles formed inside the hexagon = 6
Therefore area of hexagon = 6×(9√3)/4 = 23.38 square"
Answer is 23.38 square"
Answer:
Amir's car will cost £10348.88 after 23 years.
Step-by-step explanation:
I finally found a UK human!
This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.
The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.
16470 × 
= £10348.88
I hope that helps you!! ^-^
Answer:
Step-by-step explanation:
3y + 1 - 2y = -3 -3y
4y = -4
y = -1
This is the awnser to the problem
We have two questions, but we need to find the volume of the spherical tank first.
So the formula we will use to find the volume is:
(4/3)πr³=V
Let's fill in the information we have and solve. We will be using 3.14 for pi.
(4/3)(3.14)6³
(4/3)(3.14)(216)
4.1867×216
I'll be using the repeating decimal for 4.1867, I rounded to 7, but there is a repeating 6.
904.32
So the volume is 904.32 yards³ (or 904.78 if using the full pi)
We have to multiply the volume by 7.15.
904.32×7.15
6,465.89
It will cost $6,465.89 to fill the tank with the liquid.
