Well if it’s a square all sides are equal, so all sides are 7ft.
Perimeter=
7+7+7+7=28ft
Or
7•4=28
Hope this helps!!!
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.
-0.05 is larger. Since they're negative, you're going by which is closer to 0 rather than farther. -0.05 is closer to 0 on a number line, so it's larger than -0.25.
Answer:
