By the question,
π = 3.14
circumference = 7.42 cm
or,. 2πr. =7.42
or,. 2×3.14×r. =7.42
or,. 6.28r. =7.42
or,. r. =7.42÷6.28
∆. r. =1.18 cm
Again,
Area of circumference= πr^2
=3.14 × 1.18^2
=3.14 × 1.39
=4.37 cm^2
Answer:
they are all equivalent to 8:5
Step-by-step explanation:
that is because is you simplify 16:10 by 2 you get 8:5 and when you simplify 24:15 by 3 you get 8:5
we can convert any decimal value to a fraction by simply <u>using in the denominator a power of 10 with as many zeros as there are decimals and lost the dot above</u>, this one has one decimal, so we'll use 1 zero, and lose the dot above.

The answer to this question is B
Answer: 1 hour 35 minutes
assuming both times were p.m. or a.m. and not one of each
Step-by-step explanation:
60 minutes in an hour.
3 hours 25 minutes = 205 minutes
5 hours = 300 minutes
300-205 = 95 minutes
95 minutes = 1 hour (60 minutes) and 35 minutes
