Rectangle
l = 7.2 - 1.7 = 5.5 ft b = 3.4 ft
Semicircle
r = 1.7 ft
Shaded region = area of rectangle + area of semicircle
= l x b + πr²/2
= 5.5 x 3.4 + 3.14 x 1.7 x 1.7 x 1/2
= 18.7 + 4.5373
= 23.2373 ft²
Answer: thats right...
Step-by-step explanation:
.55*X=231 .....X=231/.55.......X= 420
In the case that a scientist cools three gases in an experiment, the change in temperature will be negative for the experiment. This is because cooling results in a temperature lower than the original temperature. For example, a gas originally at 25°C when cooled to 20°C has a temperature change of -5°C.
