The relationship between the radius, r, of a sphere and its surface area, A, is r = ( A /4 π ) 1/2. What is the radius of a sphere that has a surface area of 64π square units?

8 units

Step-by-step explanation:

Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;

r = 1/2( A /4 π )

We are to find the radius r when Area A is 64π

Substitute A = 64π  into the expression and get r as shown;

Recall that: r = 1/2( A /4 π )

r = 1/2( 64 π/4 π )

r = 1/2(16)

r = 16/2

r = 8units

Hence the radius of the sphere will be 8 units

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

answer: (yeees, you need a poet.)

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.
