Answer: It is 10 because there are 2 other faces and 8+2=10
Step-by-step explanation:
Answer:
radius r = 3 cm
height h = 10 cm
volume V = 282.743339 cm^3
lateral surface area L = 188.495559 cm^2
top surface area T = 28.2743339 cm^2
base surface area B = 28.2743339 cm^2
total surface area A = 245.044227 cm^2
In Terms of Pi π
volume V = 90 π cm3
lateral surface area L = 60 π cm^2
top surface area T = 9 π cm^2
base surface area B = 9 π cm^2
total surface area A = 78 π cm^2
Step-by-step explanation:
Cylinder Formulas in terms of r and h:
Calculate volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside)**:
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
Agenda: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Answer:
A = 907.46 
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A =
= 3.14(
) = 3.14(289) = 907.46 
Answer:
30 fruits
Step-by-step explanation:
Let
x ----> number of plums on the plate
y ----> number of apples on the plate
we know that
The ratio of the number of plums to the number of apples was 3:2
so

----> equation A
After Ed took 6 plums from the plate, the number of plums remaining on the plate became the same as the number of apples
so
----> equation B
substitute equation A in equation B

solve for y

Find the value of x

therefore
Mon put on the table

Answer:
1304.5 balance after 5 months
Step-by-step explanation:
first you subtract 400 from 1722 to find the balance she will have which is 1322. then you must multiply 3.5 x 5= 17.50. now subtract 17.50 from 1322 and you get her balance after 5 months
