Volume of a sphere= (4/3)πr³
r=radius

Data:
Volume of this sphere=113 u³
Therefore:

113 u³=(4/3)πr³
(4/3)πr³=113 u³
r³=(113 u³) / (4/3)π
r³=84.75 u³/π
r=∛(84.75 u³ /π)≈2.999...u≈3 u

Answer: the radius will be 3 units.

In the figure, GK bisects FGH

bija089 [108]

Answer:

$w = 7$

Step-by-step explanation:

Given:

m<FGK = (7w + 3)°

m<FGH = 104°

angle bisector of <FGH = GK

Required:

Value of w

SOLUTION:

Since GK bisects angle FGH, it divides the angle into two equal parts. Therefore, the following equation can be generated to find the value of w:

m<FGH = 2*m<FGK

$104 = 2*(7w + 3)$ (substitution)

Divide both sides by 2

$\frac{104}{2} = \frac{2*(7w + 3)}{2}$

$52 = 7w + 3$

Subtract 3 from each side

$52 - 3 = 7w + 3 - 3$

$49 = 7w$

Divide both sides by 7

$\frac{49}{7} = \frac{7w}{7}$

$7 = w$

$w = 7$

Gordon, Henry and Sarah share £48 in a ratio 2:3:1. How much money does each person get?

Alinara [238K]

Answer:

Gordon gets 16£, Henry gets 24£ and Sarah gets 8£

Step-by-step explanation:

Let the ratio be 2x + 3x + 1x

Total amount = £48

So;

2x + 3x + x = 48

6x = 48

x = 48 / 6

x = 8

Now

2x = 16

3x = 24

x = 8
