The surface area of hemisphere is given by:
Where r is radius of hemisphere.
We are given diameter = 250 ft.
We know that radius = half of diameter.
Radius of dome = 1/2 (250) = 125 ft.
Now let us plug the value of radius in the formula,
Surface Area of dome = 98125 square foot.
Given that,
Men drink 3000 ml of water every day.
Also, there are 29.6 milliliters in 1 Fluid Ounce.
So,
if there is 1 Oz in 29.6 ml, the total Oz in 3000 ml would be = 3000/29.6 = 101.35 Oz
1010 Oz in nearly equal to 101 oz. Therefore, option B is correct.
Answer:
10
Step-by-step explanation:
Let's call Ahmed's number x,
- If he multiplies it by 2, it becomes 2x
- He then divides it by 5 so it would be 2x ÷ 5
- The result was 4, so it would be written as 2x ÷ 5 = 4
To solve for x,
- First, multiply both sides by 5: 2x = 20
- Finally divide both sides by 2 to get x on its own: x = 10
- Answer: He was thinking of the number 10
You could also work backwards:
If he ×2 then ÷5, you would ×5 then ÷2 (doing the opposite):
Hope this helps!
