A: 100m^2
10 x 10 = 100
B: 28.274m^2
You have to do pi x r squared
So,,,
Pi x 3^2
9pi = 28.274....
C: just subtract the grass bed from the land...
100 - 28.274 = 71.72566612...
So C is 71.726m^2
Hope this helped! Have a nice day :)
Answer: 3 : 1
Step-by-step explanation:
We know that the ratio of A to B is given by :-
or A : B .
Given : Number of students having brown hair = 15
Number of students having black hair = 5
Then , the ratio of students with brown hair to students with black hair will be :-

Hence, the ratio of students with brown hair to students with black hair = 3 : 1.
Answer:
{1,-4}
Step-by-step explanation:
The two equations have different slopes, so the system is possible
y = -2x - 2
y = 2x - 6
2x - 6 = -2x - 2
4x = 4
x = 1
y = 2 - 6
y = -4
Answer:
25+(The number)
Step-by-step explanation:
6 * 5 = 30 rectangle’s area
14 - 6 = 8 triangle’s base length
bh/2 for area of a triangle
8 * 5 /2 = 20 area of the triangle
20 + 30 = 50 total area
50cm^2
