Answer:
The GCF is 2.
Step-by-step explanation:
In my opinion, one of the easier ways to find the greatest common factor of two numbers is to get the prime factors of both and multiply the common ones. The prime factorization of 8 is 2*2*2, and the prime factorization of 162 is 2*3*3 (you can make a factor tree for both of these numbers to verify this). The only common prime factor for both of these numbers is 2, which means the greatest common factor of 8 and 18 is 2.
Answer:
the number of silver medals won by Brazil is 14
Step-by-step explanation:
The computation of the number of silver medals won by Brazil is shown below:
Given that
Total number of gold and silver medal wons by Brazil was 35
And, the ratio of number of gold medals to the number of silver medals be 3 : 2
Based on the above information
The number of silver medals won would be
= 35 × 2 ÷ (3 + 2)
= 35 × 2 ÷ 5
= 14
hence, the number of silver medals won by Brazil is 14
Answer:
Area of Circle 1=>64(pi) units^2
Area of Circle 2=>9(pi) units^2
Step-by-step explanation:
Circumference=2(pi)r
Circle 1: 2(pi)r=16(pi)
Divide by 2(pi) on both sides
r=8 units
Area=(pi)r^2
Area of circle 1=>(pi)*(8^2)
Area of Circle 1=>64(pi) units^2
Circle 2: 2(pi)r=6(pi)
Divide by 2(pi) on both sides
r=3 units
Area=(pi)r^2
Area of circle 2=>(pi)*(3^2)
Area of Circle 2=>9(pi) units^2
