Here given that r= 0.8
Area of circular glass = area of circle = pi r^2
= 3.14 ( 0.8)^2 = 2.009 square meter
cost of one square meter = 4.60
cost of 2.009 square meter = 4.60 * 2.009 = 9.244
Answer $ 9.244 .
Answer:
f(3) = 71
Step-by-step explanation:
f(x) = 10(x + 5) − 9
f(3) = 10(3 + 5) - 9
f(3) = 10(8) - 9
f(3) = 80 - 9
f(3) = 71
Answer:
x = 5
Step-by-step explanation:
= 19 - x = 14
= 19 - x - 19 = 14 - 19
= -x = -5
= -x/-1 = -5/-1x
x = 5
Hope this Helps :D
