The side of a cylinder is a square 31.4cm long. The bottom area of the cylinder is () square decimeters

The circumference is 31.4 and the height is 31.4
L = Pai * 2R = 31.4, r = 5cm
So the circle area s = Pai * R ^ 2 = 25 * 3.14=
78.5cm2 = 0.785m2

Calculation of physical specific heat capacity
A metal pot with a mass of 0.2kg contains 1.5kg of water. Heating them from 10 ℃ to 100 ℃ requires 5.8 × 10 ^ 5 joules of heat. What is the specific heat capacity of the metal?
I figured it out to be about equal to

5.8 × 10 ^ 5 joules - {1.5kg * 4.2 * 10 to the third power * (100 ° C-10 ° C)} divided by 0.2 * (100 ° C-10 ° C)

The perimeter of the bottom surface of the cylinder is 6.28 decimeters, the height is increased by 2 decimeters, and the rear area is 43.96 square decimeters?

The original height is 5 decimeters, 3.14? W? W 5.7 cubic decimeters. The original volume of the cylinder is 15.7 cubic decimeters

Using cosa to express Sin & sup2; a / 2 = cos & sup2; a / 2 = Tan & sup2; a / 2=
sin²a/2= cos²a/2= tan²a/2=

Using cosa = cos & sup2; a / 2-sin & sup2; a / 2, and COS & sup2; a / 2 + Sin & sup2; a / 2 = 1; sin & sup2; a / 2 = (1-cosa) / 2; Cos & sup2; a / 2 = (1 + COSA) / 2; Tan & sup2; a / 2 = (Sin & sup2; a / 2) / (COS & sup2; a / 2) = [(1-cosa) / 2] / [(1 + COSA) / 2] = (1-cosa) / (1 + Co
