Answer:
94.2 cm
62.8 inch
Step-by-step explanation:
The circumference of a circle is 2πr, where r is the radius.
The diamater is twice the radius, d=2r.
1) 2π·15 ≈ 94.2 cm
2) r = 10 inch. 2π·10 = 62.8 inch.
Answer:
Alternate exterior angles
Step-by-step explanation:

Answer:
706.5 meters²
Step-by-step explanation:
Area of a circle is: 
'r' is the radius.
We are given the radius of 15 meters.
Using 3.14 for pi:
The area of the circle should be 706.5 meters².
<span>-9a + 139 = -1a + 59
-9a + a= 59 - 139
-8a = - 80
a = 10</span>
