The area of a circle is:
a=πr^2 dividing both sides by π
r^2=a/π taking the square root of both sides
r=√(a/π), in this case a=44 m^2 so:
r=√(44/π) m^2
r≈14.01 m^2 (to the nearest hundredth of a square meter)
Answer:
2635
Step-by-step explanation:
the first two stand for 1000
so
2000
is the first part
the second numeral stands for 100
there are 6 of them
so
600
is the second part
the third numeral stands for 10 and there are 3 of them
thus
30
is the third part
there are 5 lines so the last part is 5
so your answer is 2635
Answer: the average rate of change is 4.
Step-by-step explanation:
The average rate of change is the slope. Therefore, you must use the following formula for calculate the slope:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
As you can see in the table, when x=5, y=-2 and when x=9, y=14. Then the points you must substitute into the formula are:
(5,-2) and (9,14)
Then, you obtain:
![m=\frac{14-(-2)}{9-5}=4](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B14-%28-2%29%7D%7B9-5%7D%3D4)
Is there any option to choose from ?
If so show them and I’ll probably be able to answer .
The surface area of a sphere is given by
![A=4 \pi r^{2}](https://tex.z-dn.net/?f=A%3D4%20%5Cpi%20%20r%5E%7B2%7D%20)
where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
