I'm in algebra 1 please help i'm so lost
lesya692 [45]
Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16. 

Tl;Dr: each side is 16 feet long.

In circle D with m \angle CDE= 76m∠CDE=76 and CD=13CD=13 units find area of sector CDE. Round to the nearest hundredth.
Ksju [112]

Answer:

112.03sq. units

Step-by-step explanation:

The area of a sector = theta/360 * πr²

The area of a sector = 76/360 * 3.14 * 13²

The area of a sector = 76/360 * 530.66

The area of a sector = 40,330.16/360

The area of a sector = 112.03sq. units

This gives the area of the sector
