The area of a circle is 2,826 square centimeters. what is its diameter?

Formula to find the area of circle is:

a=πr² Where a= area and r= radius of the circle.

Given area: a=2,826 square centimeters.

So, plug in a=2,826 in the above equation to get r.

2826=πr²

Dividing each sides by π.

Since π=3.14

900=r²

√900=r

r=30

Since the diamter is twice the radius.

Hence, diameter= 2*30= 60.

So, the diameter of the circle is 60 centimeters.

900=

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
