70). Answer Letter Choice, (C), 18 pi square units.
Area = pi r^2
D = 12
R = 6
Larger Circle: 36 pi
Find smaller circles, Subtract:
Diameter of larger circle is 12
Radius 6, also diameter of small circles (2)
pi r^2
D = 6
R = 3
pi = 9
2 circles
2 * 9 pi = Letter Choice, (C), 18 pi square inches
71). Answer Letter Choice, (B), 30.79 cm^2
72). Answer: 144
Hope that helps!!!! : )
92
given 2a² + 5b²
substitute given values for a and b into the expression
2(- 6)² + 5(2)² = (2 × 36 ) + (5 × 4) = 72 + 20 = 92
Answer:
see the picture attached please
Answer:
yes
Step-by-step explanation:
Substitute the point into the equation and see if it is true
x- 5y = 10
0 -5(-2) = 10
0 +10 = 10
10 = 10
This is true so the point is a solution to the equation
You can not simplify it because they both are prime numbers
