Which would be the most appropriate way to estimate -6.1(0.22)? Check all that apply. A. Use rounding to get -6(0.2), and then multiply.
B. Use compatible numbers, such as -6(0.5), and then multiply.
C. Use the benchmark numbers -6 and 1, and then multiply.
D. Use front-end estimation to get -6(0.2), and then multiply.
E. Round the factors to the nearest whole number, and then multiply.

Step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
