What is the approximate surface area of the sphere 15yd?
tekilochka [14]
<span>The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15x15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards.</span>

A student says the first step of the proof is "Reflect △ABC in AB←→ to create △ABC′." Which of the following statements logicall
ollegr [7]

Reflecting the triangle ABC implies that the new position would be a mirror of the previous position

The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W

<h3>How to determine the next step</h3>

After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.

This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point

Hence, the statement that logically comes next is (c)

A scoop of ice cream is the shape of a whole perfect sphere sits in a right cone.
Andrei [34K]

Answer:

  10 cm

Step-by-step explanation:

The volume of a sphere is given by the formula ...

  V = 4/3πr³

The volume of a cone is given by the formula ...

  V = 1/3πr²h

The ratio of the volume of the cone to that of the sphere is ...

  Vcone/Vsphere = (1/3πr²h)/(4/3πr³) = h/(4r)

In order for the ratio to have a value of 1, we must have ...

  h = 4r

The height of the cone must be 4×2.5 cm = 10 cm to fit all of the ice cream.
