Every school kid has been told that a circle of radius r has circumference=2\[pi] r. here is a parameterization of a circle of radius r: clear[x, y,t, r]; {x[t_],y[t_]}={r cos[t],r sin[t]}{r cos[t],r sin[t]}to get the whole circle, you run t from 0 to 2\[pi].use this information to confirm that the circumference of a circle of radius r measures out to 2\[pi] r units long.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

the answer is c hope it

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
