Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) is
As = 4×pi×r²
our radius r (half of the diameter) here is 5m.
As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²
5 1/2 + p = 6
subtract 5 /12 from each side
5 1/2 - 5 1/2+ p = 6 - 5 1/2
p = 6 - 5 1/2
borrow from the 6
p = 5 2/2 - 5 1/2
p = 1/2
Answer:
didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)
Step-by-step explanation:
if ur supposed to add them then
1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2
2. 1/4 + 2/4 + 1/4 = 4/4 = 1
3. 1/8 + 8/8 + 4/8 = 1 5/8
4. 1/4 + 1/4 + 2/4 = 4/4 = 1
5. 1/4 + 1/4 + 1/4 + 1/4 = 1
A. After the mod. One wall is “x” longer than original (horizontal in diagram) and the other is “x” shorter (vertical)
(30+x)(30-x)
b. He original area = 30 x 30 = 900 sq. ft.
The mod. Area is (30+6)(30-6) = 36x24= 764 sq. ft.
So the room was largest to begin with when it was a square
