Step-by-step explanation:
You are given a rectangle that is placed around a semicircle. You are also given the width of the rectangle that is 8cm. You are asked to find the area of the shaded region. Let us assume that the semicircle is inscribed in the rectangle or inside the rectangle so that the diameter of the semicircle is the same as the side of the rectangle. Let us also assume that the shaded region are the ones not inside the semicircle.
Area of a circle = πD²/4
Area of a circle = π(8cm)²/4
Area of a circle = 16π cm²
Area of the rectangle = LW
Area of the rectangle = (8cm) ( 4cm)
Area of the rectangle = 32 cm²
Area of the shaded region = 16π cm² - 32 cm²Area of the shaded region = 18.265cm²
First, u multiply 8x3. Only the 4 can go in the ones place so put the four beneath the line and put the 2 over the 7.
Multiply 8x7 and add 2.
Move to the tens place, do 2x3 then 2x7.
Add the products and put the comma. Then ur done
