A sphere has volume 463.01 cm^3. What is the radius of the sphere? A second sphere has a radius half as long as this radius. Wha
Mumz [18]

Answer:

1: r = 2.4 cm

2: V = 57.8765 cm^3

Step-by-step explanation:

1:

The volume of a sphere is given by V = (4/3) * pi * (r^3), being 'r' its radius.

So if the volume is 463.01 cm^3, we have that:

463.01 = (4/3) * pi * (r^3)

463.01 * 3 = 4 * 3.14 * r^3

r^3 = 463.01 * 3 / (4 * 3.14) = 110.59156

r = 4.8 cm

2:

The radius of the second sphere is 4.8/2 = 2.4 cm, so its volume is:

V = (4/3) * 3.14 * (2.4^3) = 57.8765 cm^3

Please help I need help with #17, 19, and 21
viktelen [127]

Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53
