Answer: -3.4.(-2) • (-2)= -48
Step-by-step explanation: please keep in mind that every number that you multiply by 0 is equal to 0, it does not mind if number is positive or negative the result will be always 0, if we have this clear we can pass with following step.
then you do not need resolve the equation with 0 because you know that result will be 0, after that we get only one equation the first one.
-3 * 4 * (-2) * (-2)
keep in mind when you are multiplying numbers with the same sign the product will be positive, but when you are multiplying numbers with different signs the result will be negative.
we can resolve this value by value for example
-3 * 4 * (-2) * (-2)
-3 * 4= -12
then we get the following equation
-12 * (-2) * (-2)
then we can pass with the next value
-12 * (-2) = 24
then we get the following equation
24 * (-2) = -48
as you can see this will be the only one equation with a negative product.

Answer:
3.75cm 44.16cm²
20cm 314cm²
42cm 1384.74cm²
Step-by-step explanation:
Area of a circle = πr²
Where : = π = pi = 3.14
R = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
16. Radius = 7.5 / 2 = 3.75
Area = 3.14 x 3.75² = 44.16
17. Diameter = 10 x 2 = 20
Area = 10² x 3.14 = 314
18. Diameter = 21 x 2 = 42
Area = 21² x 3.14 = 1384.74
