Answer: B
Step-by-step explanation: Okay so you add 6m and 1m to get 7m for that entire side. Then you have 3m on each side that is slanted. You finally add 5m.
7m + 3m + 3m + 5m = 18m^2
37 1/2. Since the decimal is in the tens place, the best, and easiest, denominator to use is 10, which results in 37 5/10 which then can be simplified into 37 1/2
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
