X=11
All you have to do is add 5 to both sides and then divide by 5 on both sides
Answer:
88/7 ft = 12.6 ft (nearest tenth)
Step-by-step explanation:
Circumference of a circle = 2
r
<u>Radius of inner circle</u>
Given:
- circumference of inner circle = 22ft
= 22/7
⇒ 22 = 2 x (22/7) x r
⇒ r = 3.5
So the radius of the inner circle is 3.5 ft
<u>Radius of outer circle</u>
If the distance between the inner circle and the outer circle is 2 ft, then the radius of the outer circle = 3.5 + 2 = 5.5
<u>Circumference of outer circle</u>
Therefore, circumference of outer circle:
= 2 x (22/7) x 5.5
= 242/7 ft
<u>Difference between circumferences</u>
Difference = outer circle circumference - inner circle circumference
= 242/7 - 22
= 88/7 ft
= 12.6 ft (nearest tenth)
Seeing from the graph I've provided above, the correct answer would be D, the last one.
Answer:
Step-by-step explanation:
Answer:

is the volume in terms of side a
Step-by-step explanation:
Given that you I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per square foot, the material for the roof cost $2 per square foot, and the material for the sides cost $2.50 per square foot; and I spent $450 altogether on material for the shed.
Let a be the side of square and h be the height
Total cost of materials = cost for floor + cost for roof + cost for sides
= area of floor (4) + lateral area (2.50)+roof area (2)


Now coming to volume
Volume = V = lbh =
