Answer:
330ft²
Step-by-step explanation:
Area of figure = Area of rectangle + Area of semicircle
= lb + pi r²/2
= 10 x 8 + 3.1 x 4 x 4/2 ( as 8 is diameter)
= 80 ft² + 248 ft²
= 328 ft² => 330ft²
Answer:The reciprocal of 5/6 is found by switching the numerator for the denominator and the denominator for the numerator. That means that the reciprocal of 5/6 is 6/5.
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
