1. Consider the parallelogram ABCD drawn in the 1. figure attached.
2. The diagonals of a parallelogram bisect each other, so AM=MC and BM=MD
3. In triangle ABC, BM is an altitude (BM perpendicular to AC), but also a median (AM=MC). An altitude is also a median only when the triangle is isosceles, so AB=BC
similarly, in triangle BCD, CM is both an altitude and a median.Thus, BCD is an isosceles triangle so BC=CD.
4. AB= DC (opposite sides of a parallelogram are equal), similarly BC=DA
5. So ABCD is a quadrilateral, with all 4 sides equal in length. Thus ABCD is a rhombus.
The answer it b your welcome
Answer:
Yes, the farmer have enough paint to complete the job.
Step-by-step explanation:
It is given that a gas storage tank is in the shape of a right circular cylinder.
The radius of the base is 2 ft and the height of cylinder is 3 ft.
The total surface area of a cylinder is
Total surface area of gas storage tank is
The total surface area of gas storage tank is 62.83 square feet.
The farmer has 1 gallon of paint and 1 gallon of paint will cover 162 square feet.
Since 62.83<162, therefore 1 gallon of paint is enough to paint the gas storage.
Hence the required statement is Yes, the farmer have enough paint to complete the job.
