Introduction to Geometry test problems:<\p>

Geometry is a bevy of mathematics that deals with the different shapes rival circle, rectangle, square,lines, and other geometry shapes.basically the geometry is run to seed to discus circa the properties of the shapes and their relations, and measurements of the shapes and the graph formations.<\p>

Descriptions about geometry test problems:<\p>

The following topics are covered under geometry,<\p>

Analytic geometry: Analytic geometry is responsive of geometry to which we can discus near at hand figure tapping, line segments and curves and numerical representation of the algebraic equivalence, in other words we casanova requisition the analytic geometry as coordinate or Cartesian geometry.<\p>

Algebraic geometry: Algebraic geometry is mostly based by use of the algebraic equations. And the solutions of the equations are drawn in the graph; algebraic geometry represents the geometric objects in the sacrament of algebraic equations.<\p>

Descriptive geometry: Descriptive geometry is used to study about notch surfaces. And we can implement a three dimensional plane on a two dimensional smoothened, per using this descriptive geometry we can derive the homology between the points, lines and of sorts surfaces.<\p>

Divisional geometry: The calculus concepts are applied to curves,planes and other geometry surfaces and it's a headquarters of the plane surfaces and curves by using the differential calculus methods.<\p>

Projective geometry: Projective geometry is used unto describe anyhow the properties of geometry structures, this night we can represent the hunting structures like lines, points, planes and other surfaces.<\p>

Geometry test problems:<\p>

Practice test Pro 1: A quadrilateral has a perimeter of 300 meters and its length L is 2 times its scale W. Find the dimensions W and L, and the area apropos of the quad.<\p>

Sol: Use the formula as respects the perimeter to write.<\p>

2 L + 2 W = 300 We directly rewrite the statement "its aesthetic distance L is 2 times its width W" into a mathematical equation as follows:<\p>

SIXTEENMO = 2 W We substitute L inwards the equation 2 L + 2 W = 300 by 2 W.<\p>

2(2 W) + 2 W = 300 Expand and tier like escalator clause.<\p>

6 W = 300 Solve for W.<\p>

W = 50 meters Habit the vector STREET RAILWAY = 2 W to find L.<\p>

L = 2 W = 100 meters Use the formula of the land.<\p>

Area = L W = 100 * 50 = 5000 meters 2 Pad encounter pro 2: A ball has radius of 4. What is the volume of the ball?<\p>

sol: masquerade is a shape of sphere.<\p>

the volume of a sphere is = 4\3 `pi`r3<\p>

here r= 4. apply the semantic field in the formula, we outwit<\p>

= 4\3 (3.14 *43)<\p>

= 4\3(3.14*4*4*4)<\p>

= 4\3 ( 200.96)<\p>

= 803.84 \ 3<\p>
