Answer:
Area of shaded part = 113 mm² (Approx.)
Step-by-step explanation:
Given:
Diameter of Semi-circle = 24 mm
Find:
Area of shaded part
Computation:
Radius of semi-cicrle = Diameter of Semi-circle / 2
Radius of semi-cicrle = 24 / 2
Radius of semi-cicrle = 12 mm
So,
Radius of small circle = 12 / 2
Radius of small circle = 6 mm
Area of shaded part = Area of semi circle - Area of small circle
Area of shaded part = [πR² / 2] - [πr²]
Area of shaded part = [(3.14)(12)² / 2] - [(3.14)(6)²]
Area of shaded part = [(3.14)(144) / 2] - [(3.14)(36)]
Area of shaded part = 226.08 - 113.04
Area of shaded part = 113.04
Area of shaded part = 113 mm² (Approx.)
Answer:
Cross products.
Step-by-step explanation:
In the proportion a/b = c/d the products a•d and b•c are usually called cross products.
<span>29.26 inches.
Since the object Robbie drew is a square, we know that all 4 sides are the same length and the area of the square is L^2, where L is the length of one side. So
A = L^2
856 in^2 = L^2
sqrt(856 in^2) = l&2
29.26 in = L
So the length of one side is approximately 29.26 inches.</span>
