Answer:
the answer is C: 1932 sq. cm
Step-by-step explanation:
You want to break down the sections (which is double for each)
there are 6 rectangles but you will only need to calculate for 3
1st rectangle
a = (25) (12)
a = 300 sq. cm
**then multiply by 2 = 600 sq. cm**
2nd rectangle
a = (12) (18)
a = 216 sq. cm
then 216 * 2 = 432 sq. cm
3rd rectangle
a = (25) (18)
a = 450 sq. cm
then 450 * 2 = 900 sq. cm
Total Surface Area
SA = 600 sq. cm + 432 sq. cm + 900 sq. cm
SA = 1932 sq. cm
To grandparents house :
140/56 = 2.5 hours
Return trip :
140/50 = 2.8 hours
Total time : 2.8+2.5 = 5.3 hours
Answer:
20,939.00 ft²
Step-by-step explanation:
To solve this you first need to find the radius of the circle.
Circumference (C) = (2)radius (r)
163.28=2r
163.28/2=2r/2
81.64=r
Area of a circle (A) = πr²
A=π(81.64)²
A=π(6665.0896)
A=20938.99652
This can be simplified to 20,939.00 ft²
