What is the surface area of a sphere whose volume is 28811 ins , n

Mathematics

Volume=(4/3)pir^3
volume=288pi
288pi=(4/3)pir^3
divid eobht sides by pi
288=(4/3)r^3
multiply both sides by 3/4 to clear fraction (4/3 times 3/4=12/12=1)
216=r^3
cube root both sides
6=r

surface area=4pir^2
surface area=4pi6^2
surface area=4pi36
surface area=144pi in^2

Turn the written information into a equation (exponential function):
zmey [24]

Step-by-step explanation:

common ratio is usually used for geometric sequences.

every term is created by multiplying the previous term by a certain constant factor (= common ratio).

this factor or common ratio is in our case 4.

such a sequence is a function f(x) for x being whole numbers.

a0 = 1

a1 = a0×4 = 1×4 = 4

a2 = a1×4 = 4×4 = 16

...

an = 4^n

as general function that is then

f(x) = 4^x

a horizontal shift right by 6 units means that now the functional value of x is the same as it was for (x-6) before the shift.

e.g. f_new(6) = f_old(0)

so, the function is

f(x) = 4^(x - 6) or (4^x)/4⁶

Find the Area of the Shaded Region. Triangle A = bh/2. Rectangle A = bh
storchak [24]

Answer:

Step-by-step explanation:

From the diagram in the image attached:

Base of triangle = 20cm - ( 4 + 3)cm

Base of triangle = 20 - 7 = 13cm

Height = 9cm

Area of triangle = (0.5) × base × height

Area of triangle = 0.5 \times 13 \times 9 = 58.5cm^2

Area of rectangle = Length × width

Area of rectangle = 20 \times 9 = 180

Shaded area = area of rectangle - area of triangle

Shaded area = 180cm^2 - 58.5cm^2

Shaded area = 121.5cm^2
