Ede4ka [16]

Answer:

volume of cube share box = 67.92 inch²

Step-by-step explanation:

given data

soccer ball volume = 85.3π cubic inches

solution

we know that ball will fit inside the box when box length will be equal to diameter of ball

and here soccer ball volume will be express as

soccer ball volume = $\frac{4}{3}\times \pi \times r^3$ .................1

85.3π = $\frac{4}{3}\times \pi \times r^3$

solve it we get

r³ = 69.9765

r = 4.12 inch

so diameter = 2 × 4.12 = 8.24 inch

diameter = length of box side

volume of cube share box = a²

volume of cube share box = 8.24²

volume of cube share box = 67.92 inch²

If you take out a loan for $4,000 and you will owe $4,920 after 2 years, what is the rate of simple interest? Express your answe

11111nata11111 [884]

Answer:

11.5

Step-by-step explanation:

Simple interest formula:

$I=P\cdot r\cdot t,$

where

I = interest

P = principal

r = rate

t = time

In your case,

P = $4,000

I = $4,920 - $4,000 = $920

t = 2 years

So,

$920=4,000\cdot r\cdot 2\\ \\r=\dfrac{920}{2\cdot 4,000}=0.115$

The rate as decimal is 0.115 that is 11.5% as percent
