Estimation A machine drills a hole into a sheet of aluminum. The radius of the hole is exactly 2.43 in. Round the radius to the nearest inch to estimate the area of the hole. Then find the area of the hole using the exact radius. Use 3.14 for a in both calculations. in ? Using the rounded radius, the area of the hole is about (Round to the nearest hundredth as needed.)​

Step-by-step explanation:

Round to 2 inches

A = π(2²) = 4π = 4(3.14) = 12.56 in²

A = π(2.43²) = 18.541386 ≈ 18.54 in²

i dont know if you cant find a way its best to actually add all of them start from 105 tho

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
