Find the volume of a cylinder with a radius of 5 cm and a height of 10 cm. Then, find the volume of the cylinder if the radius i s increased to 10 cm. Leave your answers in term of pi.
2 answers:
Well pi times radius squared so 25* 3.14=78.5 * height so 78.5*10=785 is the answer for the first one so for the second take pi times radius squared so 100*3.14=314*10 = 3,140 1st answer 785cm squared 2nd answer 3,140cm squared
Answer:
250π
1000π
Step-by-step explanation:
(refer to attached)
volume of cylinder is given by:
V = π r²h,
where r = radius of base and h = height of cylinder
Given r = 5 and h = 10, hence
V = π r²h
V = π (5)²(10)
V = π (25) (10)
V = 250π (answer)
For the second case, r = 10 cm
V = π r²h
V = π (10)²(10)
V = π (100) (10)
V = 1000π (answer)

Answer:
5/8 = 20/32
Step-by-step explanation:
if you multiply the denominator and the numerator of 5/8 by 4 it will equal 20/32
The answer is 0 because if you substitute x with 1 and solve the equation you get 0
it's 88.1 x 10 to the power negative 2
and
0,0881
Step-by-step explanation:
88.1÷1000=0,0881
