Answer:
Step-by-step explanation:
Diameter = 14 cm
r = 14/2 = 7 cm
Outer surface area of hemisphere =2πr²
= 2π*7*7
= 98π cm²
The answer to the question is 1.9 million in 1950.
Original Ratio of 1 in = 7 ft so 3 in = 21 ft
Now, New ratio 1 in = x ft so 3 in = 27ft
1/x = 3/27
cross multiply a/b = c/d ad = bc
1/x = 3/27
3x = 27
x = 9
1 in represents 9 ft
Answer:
B, C E and F
Step-by-step explanation:
The inequality is x > -30
the numbers belonging to the solution are all on the heavy line.
Note -30 is not included because of the clear circle on -30
also -44 is not on the heavy line.
