Answer:
13
Step-by-step explanation:
The formula for cirmference is
C= π2 * r
we're using 3.14 as pi and r = radius.
the radius is always half of the diameter.
So in this case since the diamter is 4, the radius is 2. let's substitute these numbers.
C= 3.14 *2*2 and there your answer is 12.56 which rounded to the nearest tenth is 13.
Hope this helps :)

Answer:
The weight : 29 pound
Alan would pay for his dinner : $130
Step-by-step explanation:
Let x represent the weight of the lobster
the cost of the dinner at restaurant 1 is 4x + 14
the cost of the dinner at restaurant 2 is 3x + 43
Now ,we have to solve the equation : 4x + 14 = 3x + 43
4x + 14 = 3x + 43
⇔ x = 43 - 14
⇔ x = 29
In this case Alan would pay the same amount for his dinner at any restaurant:
the price = 4×(29)+14 = 130
= 3×(29)+43 = 130.

Answer:
(B) 1.2 > -6.9
Explanation:
The negative numbers/decimals are always to the left of the 0 on a number line. They are not positive.
The positive numbers are always to the right of the 0 on a number line. They are always greater than negative numbers.
6.9 might be greater than 1.2 if it is a positive number, but if it is a negative number, 1.2 is greater.
Answer:
80cm^3
Step-by-step explanation:
To find the volume of the figure, we can see the shape comprises of both cube and cuboid
Volume of cuboid = length x breadth x height = 6x4x3= 72cm^3
Volume of cube = length xlength x length = 2×2×2 = 8cm^3
The volume of the figure = volume if cuboid and cube = 72+8 = 80cm^3
