Answer:
A≈102.07035
Step-by-step explanation:
A =π * r^2=π · 5.7^2 ≈ 102.07035
Answer:
220
Step-by-step explanation:
We have given that Colin scored 25 and Brian scored x ( x-unknown)
Since we know that Brian scored 170 more than Colin, Brian scored:
x = 25 + 170 = 195
Now we know that Colin scored 25 and Brian scored 195.
They together scored
25 + 195 = 220
The value of "x" is 5.5
<em><u>Solution:</u></em>
Given that we have to solve the proportion

We can solve the above given proportion for "x" by cross multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable "x"

On rounding to nearest tenth we get 5.5
Thus value of "x" is 5.5
