Maybe 28kms in 1 hour
Or 2,8kms because 7/10 is 0,7km
Answer:
(x + 2)² + (y − 9)² = 36
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
Here, the center is (-2, 9) and the radius is 12/2 = 6.
(x + 2)² + (y − 9)² = 36
Hey there!
2 1/4 = 9/4
3 1/2 = 7/2
9 x 7 = 63
4 x 2 = 8
= 63/8
Simplifying 63/8 . . .
63/8 = 7 7/8
2 1/4 * 3 1/2 = 7 7/8
Area = 7 7/8
I hope this helps you!
Answer:
Area = 50.24 units²
Circumference = 25.12 units
Step-by-step explanation:
Circumference
Area
Area
∴ The circumference of the circle is 25.12 units, and the area of the circle is 50.24 units²
Hope this helps :)
