Answer: perimeter = 70.54 cm
Step-by-step explanation:
Perimeter of a shape is the distance around it.
Perimeter of the arc of the bigger semicircle is
π × r
= 3.14 × 7 = 21.98 cm
Perimeter of the arc of the smaller semicircle(handle) is
π × r
= 3.14 × 3 = 9.42 cm
Perimeter of the arc of the smallest semicircle(inner part of the handle) is
π × r
= 3.14 × 1 = 3.14 cm
Therefore, the perimeter of the shape would be
21.98 + 9.42 + 3.14 + 7 + 7 + 10 + 10 + 2 = 70.54 cm

The solution of the expression is -1 ⇒ 3rd answer
Step-by-step explanation:
Let us revise some important rules on the number line
- If we add number to another number we move to right
- If we subtract a number from another number we move to left
∵ The expression is negative 2 minus 3 minus (negative 4)
∵ negative 2 = (-2)
∵ minus means (-)
(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5
∴ (-2) - 3 = -5
∵ minus (negative 4) = - (-4)
- Remember (-)(-) = (+)
∴ minus (negative 4) = + 4
That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1
∴ -5 + 4 = -1
∴ The expression (-2) - 3 - (-4) = -1
The solution of the expression is -1
