Answer:
B
Step-by-step explanation:
In terms of diameter (d), the area (A) of a circle is given by the formula
A = (π/4)d²
You have d=20 yd, so the area of the circle is
A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
A = 100π yd² . . . . . . . . do the arithmetic
A ≈ 314.16 yd²
43 and 44, but it's closer to 43
Answer:
82 degrees.
Step-by-step explanation:
3r=10+5s
3(10)=10+5s
30=5s
-10
20=5s
4=s
the value of s is 4 when r equals 10
