Find (4.2) x (1.6) by drawing an area diagram or using another method. Show your reasoning. Pleae answer this I really need help. PLZ

the answer is 6.72

Step-by-step explanation:

Instead of a diagram you can do 4.2 times 1.6 and after you finishes doing that You put the decimal 2 times and you should get 6.72

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

answer:

your answer is: c. 196 7/8 in^3.
