Abasketball team wants to paint half of a free-throw circle grey. if the circumference of the free-throw circle is 30.77 feet, what is the area that will be painted grey? use 3.14 for π, and round to the nearest square foot. enter your answer in the box.

Step-by-step explanation:

Given : The circumference of the free-throw circle is 30.77 feet.

To Find: what is the area that will be painted grey?

Solution:

Circumference of circle =

Since we are given that circumference of the free-throw circle is 30.77 feet.

So,

A basketball team wants to paint half of a free-throw circle grey.

Area of half of circle =

Area of half of circle which is painted grey =

                                                                        =

Hence the area that will be painted grey is

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
