Given:

The diameter of a sphere is 19 cm.

To find:

The volume of the sphere.

Solution:

We have,

Diameter=19\text{ cm}

Radius=\dfrac{19}{2}\text{ cm}

The volume of the sphere is

V=\dfrac{4}{3}\pi r^2

where, r is radius.

Putting \pi=\dfrac{22}{7}, r=\dfrac{19}{2} in the above formula.

V=\dfrac{4}{3}\times \dfrac{22}{7}\times (\dfrac{19}{2})^3

V=\dfrac{4}{3}\times \dfrac{22}{7}\times \dfrac{19}{2}\times \dfrac{19}{2}\times \dfrac{19}{2}

V=\dfrac{75449}{21}

V=3592.80952

V\approx 3592.8

Therefore, the volume of the sphere is 3592.8 sq. cm.

Jose has 1000$ in his savings account. it pays out 5% interest what is his balance after 1 year
NARA [144]

The most appropriate choice for simple interest will be given by- Balance of Jose after 1 year is $1050

What is simple interest?

Simple interest is the interest applied on the principal value after charging some certain percentage of rate for some certain amount of time.

If the principal value is p, rate is r % per annum and time is t years

Simple interest is calculated as

SI = p ₓ r ₓ t / 100

Here,

Principal for Jose = $1000

Rate = 5%

Time = 1 year

Simple interest = 1000x5x1/100

                         = $50

Amount = $(1000+50)

             = $1050

Balance of Jose after 1 year is $1050

What is the measure of KPN?
Debora [2.8K]

Answer:

angle KPN=95 degree

Step-by-step explanation:

angle KPN = angle JPO (because they are vertically opposite angles)

Now,

angle JPO+angle LOP=180 degree(being co interior angles)

angle JPO + 85 =180

angle JPO =180-85

angle JPO =95

since angle JPO is equal to KPN ,angle KPN is 95 degree
