The total area of a circle is pi * radius^2
The total area of the circle is pi x 5^2 = 25pi sq. cm.
2/5 of this is success, so the answer is 2/5 * 25pi = 10 pi sq. cm.
First, you need to simplify these fractions:
4/12 = 1/3
A. is definitely the same as 4/12.
B: 12/30 = 2/5
C: 8/24 = 1/3 - this is also the same as 4/12
D: 16/48 = 1/3 this is also the same as 4/12
This means that the fraction not equivalent to 4/12 is B. 12/30
Answer:
1/9
Step-by-step explanation:
A man enters a tall tower, needing to know its hieght. He notes that a long pendulum extends from the ceiling almost tothe floor and that its period is 15.5s. (a) How tall isthe tower? (b) If this pendulum is taken to the Moon,where the free-fall acceleration is 1.67m/s2, what isthe period there?T=15.5s(a) L=T2g/4π<span>2</span>
