Answer:
Step-by-step explanation:
Diameter = 6 units
Radius = Diameter/2 = 6/2 = 3 units
Taking π=3.14
Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c
c = 18.84
Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b
b = 28.26
So,
b + c = 28.26 + 18.84 = 47.1
(t - 7)³
(t - 7)(t - 7)(t - 7)
(t² - 7t - 7t + 49)(t - 7)
(t² - 14t + 49)(t - 7)
(t³ - 7t² - 14t² + 98t + 49t - 343)
t³ - 21t² + 147t - 343
The answer is B. Multiply
