Answer:
A = 94.985
Step-by-step explanation:
Formila for area of a circle is A = pi * radius²
Just plug in your numbers for: A = 3.14 * 5.5²
The radius is 5.5 because the diameter is 11
A = 94.985
A = 1/6(4^2 x 3.14)
A = 1/6(16 x 3.14)
A = 8.37
A = 8.4
answer
8.4
Answer:
The answer is C
Step-by-step explanation:
2x + 4y
2 x 3 = 6
4 x 6 = 24
24 + 6 = 30
The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore, the age of the grandson is 7 years.
<h3>How to use equations to find the age?</h3>
A grandson's age in months is equal to his grandfather's age in years.
Recall,
12 months = 1 year
Hence,
let
x = age of grandson in month
It is the same age in years for the grandfather.
Therefore,
x = age of grand father in years
The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore,
x - x / 12 = 77
12x - x/12 = 77
11x / 12 = 77
cross multiply
11x = 924
x = 924 / 11
x = 84
Therefore, the grandson age in in years is 84 / 12 = 7 years.
