The volume of a sphere is 38808cm cube find its radius

Volume of sphere = 4/3 pi. r^3

38808 = 4/3 x 22/7 x r^3

11 x 3528 = 4/3 x 22/7 x r^3

3528 =4/3 x 2/7 x r^3

4 x 882 = 4/3 x 2/7 x r^3

882 = 2/21 x r^3

r^3 = 882 x 21 /2 = 441 x 21

= 21 x 21 x 21

hence ,

r = 21 cm

now,

surface area = 4 pi. r^2

= 4 x 22/7 x 21 x 21

= 4 x 22 x 3 x21

= 88 x 63 =5544 cm^2

Hope this helps! :)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
