Answer:
$520.96
Step-by-step explanation:
This is a compound shape made of 1 rectangle and two semi circles which makes 1 full circle.
Area of Rectangle = L x W
Area of circle is =pi x radius squared
Area of Rectangle is 5ft x 4ft = 20 ft squared.
Area of circle is = 12.56 ft squared
- Diameter of the circle is 4ft, radius is 1/2 diameter
- Radius is 2ft, 2 x 2 = 4ft
(pi) 3.14 x 4ft = 12.56 ft squared.
As it is a compound shape you need to add
Area of Square + Area of circle =
20 ft squared + 12.56 ft squared =
Total Area of window is 32.56 ft squared
$16 = 1 square foot
$16 × 32.56 = $520.96
Answer:
the answer s hard
Step-by-step explanation:
Answer:
Combine points A with C and A with B. Consider ΔABD and ΔACD:
1. AD is common side, then AD\cong AD;
2. CD\cong BD - given in the diagram;
3. \angle ADB\cong \angle ADC .
By SAS Postulate, \triangle ABD\cong \triangle ACD . Congruent triangles have congruent corresponding sides and congruent corresponding angles, so AC\cong AB .
From this proof you can see that correct choice is option D (In triangles ABD and ACD, two sides and an included angle are equal.)
