Simple interest is $ 9

<em><u>Solution:</u></em>

Given that,

P = $ 400

R = 9 \% = \frac{9}{100} = 0.09

T = 0.25 years

<em><u>The formula for simple interest is:</u></em>

I = P \times R \times T

Where,

I is the simple interest earned

R is the rate of interest in decimal

T is the number of years

<em><u>Substituting the values we get,</u></em>

I = 400 \times 0.09 \times 0.25\\\\I = 36 \times 0.25\\\\I = 9

Thus simple interest is $ 9

To answer this question, you would need a protractor, which is a device that measures angle. Because this is a picture, I cannot help you. I'm sorry....

What I can tell you is that the angle is less than 90 degrees.

Answer:

The answer is

\frac{1372}{3} \pi \:  {cm}^{3}

Step-by-step explanation:

First you have to find the radius of sphere by dividing diameter by 2 :

radius = diameter \div 2

Let diameter = 14,

radius = 14 \div 2

radius = 7 \: cm

Next you have to use the volume of sphere formula :

v =  \frac{4}{3}  \times \pi \times  {r}^{3}

Let r = 7,

v =  \frac{4}{3}  \times \pi \times  {7}^{3}

v =  \frac{4}{3}  \times \pi \times 343

v =  \frac{1372}{3} \pi \:  {cm}^{3}
