Answer is 75.4 m^2……….
scZoUnD [109]3 years ago

Answer:

75.4m²

Step-by-step explanation:

The shape shown is a cylinder

The volume of a cylinder can be calculated using this formula:

V=\pi r^2h

where r = radius and h = height

The cylinder shown has a radius of 2m and a height of 6m

Using this information we plug in the values into the formula

V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822

So the area of the cylinder is 75.39822

Our final step is to round to the nearest hundredth

The final answer would be 75.4m²

Area of triangle where A=50, b=31, c=18
Mrac [35]
Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]

This will NOT form a triangle.  The longest side (50) is greater than the sum of the other 2 sides.
