Enter you answer and show all the steps that you use to solve this problem in the space provided. estimate the area of the circle with a radius of 28 cm. use for π.

me! i've been stuck on this and have had it overdue for over 2

you so much, have a great day < 3

estimate:2571.4

actual:2464

Step-by-step explanation:

1) Area of a circle formula:

pi*r^2

pi=22/7

radius=28 cm

so

22/7*28^2=

22/7*784/1=17248/7

17248/7= 24694

THIS IS THE EXACT VALUE

EStimate is

20/7*30^2=

20/7*900=18000/7

2571.4

2464 AND 2571.4 ARE CLOSE ENOUGH SO I WOULD USE 20/7*30^2 AS MY ESTIMATE HOPE THIS HELPS!

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.
