Answer: 11
Step-by-step explanation:
when the question asks you what is the BASE of the EXPRESSION it means that the base is always the BIGGER number which is 11 and the power which is ALWAYS ON THE TOP RIGHT which is 12
hope that helps
Answer:1.570796327
Step-by-step explanation:
Answer:
Step-by-step explanation:
we are given
Calculation of A(4):
we can plug x=4
Since, this curve is below x-axis
so, the value of integral must be negative
and it is quarter of circle
so, we can find area of quarter circle
radius =4
Calculation of A(8):
we can plug x=8
we can break into two parts
now, we can find area and then combine them
Calculation of A(12):
we can plug x=12
we can break into two parts
now, we can find area and then combine them
Calculation of A(14):
we can plug x=14
we can break into two parts
now, we can find area and then combine them
Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2
Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2
Difference = larger are - smaller area
Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2
Answer: About 251 ft^2
Step-by-step explanation:
calculate
64 – 28 – 41 – 20 + 24 + 12 + 10
