Do not multiply by pi. Just use the whole number and do not try to include pi in the
IrinaK [193]

Answer:

Surface area = 1808.64in² and volume is 7234.56in³

Step-by-step explanation:

The figure above is a sphere, and it has a diameter of 24in

Radius = ?

Radius = diameter / 2

R = 24 / 2

R = 12in

Surface area of of sphere = 4πr²

Volume of a sphere = 4/3 πr³

π = 3.14

1. Surface area = 4 * 3.14 * 12²

Surface area = 4 * 3.14 * 144

Surface area = 1808.64in²

2. Volume of the sphere = 4/3πr³

Volume = 4/3 * 3.14 * 12³

Volume = 4/3 * 3.14 * 1728

Volume = 7234.56in³

The surface area of the sphere is 1808.64in² and the volume is 7234

56in³

scoray [572]

Answer:

6.93 cm

Step-by-step explanation:

You have a right triangle (90°), so you do as follow:

If I understand correctly, you are looking for the hypotenuse so

cos(30) = \frac{PQ}{QR} = \frac{8 cm}{QR}

That is equal to QR = cos(30)*8 cm = 6.928 cm
