Answer:
9 miles
Step-by-step explanation:
Answer: I don’t have my calculator on me but I’ll explain
Step by step: the shape is a cone and a sphere so the volume of a sphere is 4/3 πr^3 but because it’s half a sphere, divide by 2 and the volume of a cone is 1/3h πr^2
Sphere= 4/3 π(10)^3 (plug that in ur calculator) then divide by 2
Cone= 1/3(24) π(10)^2
Then add them together
I think the answer is false i hope im right.

In a 45 - 45 - 90 triangle the two smaller sides are =. So when you use
a^2 + b^2 = c^2, you need a and b both to find the area.
So call both of them = b^2.
Equation and solution
a^2 + b^2 = c^2
b^2 + b^2 = c^2
2b^2 = c^2
c = 24
b = ???
2 b^2 = 24^2
2 b^2 = 576 Divide by 2
b^2 = 288 I'm going to leave this as it is for the moment. You'll see what in a second.
Area of a triangle
Area of a triangle = 1/2 h * b
But the height and base are the 2 smaller equal sides of a 45_45_90 triangle
so h = b
base = b
Area of a triangle = 1/2 b^2 The equalities above tell you that. h and b of the triangle are equal.
Area = 1/2 288 feet^2
Area = 144 feet^2
