A circle has a radius of 6 ft.
den301095 [7]
I'm assuming that 5π3 is in fact 5π/3

convert radian to degrees:

5π / 3 = 5(180°) / 3 = 900° / 3 = 300°

Area of the circle = π r²
A = 3.14 * (6 ft)²
A = 3.14 * 36 ft²
A = 113.04 ft²

Area of the sector:

113.04 ft²  * 300°/360° = 94.2 ft²

The area of the sector formed by a central angle measuring 5π/3 radian is 94.2 ft²

Exponential Growth problem.
xxMikexx [17]
It will be understood that population 6,000 billion (6*10^12) in 2017.
If this is not the case, follow the logic and the final number can be adjusted easily.

Mathematical answer:
In 2017: 6,000 billion=6000*10^9 =6*10^12
rate of increase = 1.3% per year (assumed constant)
final year = 2100
Population estimate in 2100
=6*10^12*(1.013^(2100-2017))
=6*10^12*(1.013^(83)
=6*10^12*(2.921352509198383)
=17.528*10^12
=17,528 billion.

56+34=n+30? Do you add 56+34 =90-30=60 n=60?
slamgirl [31]

You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.

90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.

60 = n is the answer.
