4n + 5n + 6 + 8n -12 + 9n +2 = 360 degrees

26n -4 = 360
26n = 364
 n = 14 degrees


 Angle A = 56
 AngleD = 76 
Angle C = 100 
Angle B = 128 
TOTAL = 360

1. Solve for N
Add all terms together and set equal to 360
(4n)+(9n+2)+(8n-12)+(5n+6)=360
26N= 364
N= 14
M<A = 4(14)= 56
2.9(14)+2=128
3. 8(14)-12= 100
4. 76

The figure is made up of a cone and a cylinder.

professor190 [17]

Answer:

38 mm³

Step-by-step explanation:

Calculate the volume of the cylinder and of the cone separately.

1. Volume of cylinder

The formula for the volume V of a cylinder is

V = πr²h

Data:

D = 4 mm

h = 2 mm

Calculations:

a. Calculate the radius

D = 2r

r = D/2 = 4/2 = 2 mm

b. Calculate the volume

V = 3.14 × 2² × 2 = 25.12 mm³

2. Volume of cone

The volume for the volume (V) of a cone is

V = ⅓πr²h

V = ⅓ × 3.14 × 2² × 3

V = 18.85 mm³

3. Calculate the total volume

V = 25.12 mm³ + 12.57 mm³ = 38 mm³

Mars Take 686 Days To Orbit the sun. What percent of this time does the Earth take to orbit the sun

DiKsa [7]

All you want to do is find what 686-365 is because that's the percent increase. Next you divide the number that you got by 365 and that's your percentage increase.
