A circle has a radius of 3.93 inches. Using the correct number of significant digits, find the circumference and the area of the
circle.
The circumference is ____ in.
The area is ____ in.
1 answer:
Answer:
The circumference is 24.69 in.
The area is 48.52 in.
Step-by-step explanation:
- Circumference rule => Cf=2πr
So, Cf=2π(3.93)=24.69in
So, A=π(3.93)^2=48.52in

Answer:
3:4
Step-by-step explanation:
(1/7)/(4/21) = (1/7)×(21/4) = 3/4 = 3:4
Answer:
3.24 minutes
Step-by-step explanation:
Use a calculator or chart to find the z-score.
P(Z > z) = 0.60
P(Z < z) = 0.40
z = -0.253
Find the time associated with the z-score.
z = (x − μ) / σ
-0.253 = (x − 4) / 3
x = 3.24
