What is the radius of a sphere that has a volume of 5575.28m3?

a.

Height = 31 cm

Base = 20 cm

b.  310 cm (given)

c.  See Below

Step-by-step explanation:

a.

Let height be "h" and base be "b"

Area of triangle is:

Area = 0.5 * height * base

THe height is 11 more than base, so we can say:

h = b + 11

So, we have:

Area = 0.5 * b * h

310 = 0.5 * b * (b+11)

Solving for b:

So,

h = 20 + 11 = 31

Height = 31 cm

Base = 20 cm

b.

The area of the triangle is already given as 310 cm

c.

The perimeter is sum of all the sides.

We aren't given whether this is right triangle or not.

So we can't know the third side.

No angle is also given,

Also, the height is one side or perpendicular distance from one vertex to another side, we don't know. So we cannot figure the perimeter out.
