Answer:

150.72 mm^3

Step-by-step explanation:

volume = (pi)(r^2)h

volume = 3.14 * (4 mm)^2 * 3 mm

volume = 3.14 * 16 mm^2 * 3 mm

volume = 150.72 mm^3

The area of a circular plate is 625pi sqaure in. If the radius of the plate is tripled what is the new area
goldenfox [79]

Answer:

5625in²

Step-by-step explanation:

Area of the plate = πr²

625π = πr²

625 = r²

r = √625

r = 25in

If the radius of the plate is tripled, then the new radius will be 3(25) = 75in

New Area = π(75)²

New Area = 5625π in²

If the radius is tripled, the new area of the plate is 5625in²

1)When adding two negative numbers, _________ the absolute value of the numbers and keep the negative sign.
butalik [34]


1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3


2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3


3) change
for example 3 - (- 2) = 3 + 2


4) -10

the sum is -10.25, which is closest to -10
