Answer:
<em>Circumference:</em> 18.84 cm
<em>Area:</em> 28.26 cm^2 (exponent 2)
Step-by-step explanation:
Circumference = 2(pi)r
The diameter is 6. Means the radius is 3 (half of 6)
pi = 3.14
2(3.14) x 3 = 18.84
Circumference is 18.84 cm.
Area of a circle = (pi)r^2
(3.14)(3)^2 = 28.26 cm^2 (exponent 2)
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
