Answer: V= 330.513 cm 3
Step-by-step explanation:
Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so
8.7 x 8.7 = 75.69cm^2
75.69 x 13.1 = 991.539
991.539 ÷ 3 = 330.513 cm^3
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
Answer:
Option A is correct.
4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5
Step-by-step explanation:
Given the expression: 
If n = -5
then, by substituting in given expression we get;

Option A:
4n + 8
Substitute the value of n = -5 we have;

Option B:
2n + 2
then;
2(-5) + 2 = -10 + 2 = -8
Option C :

then;

Option D:
n + 8
then;
-5 + 8 = 3
Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
Slope is always (y2-y1)/(x2-x1) in this case:
(-2-3)/(6--4)
-5/10
-1/2
