A cylinder and its dimensions are shown below.

12.1 cm

3.8 cm

One equation for calculating the volume of a cylinder is V=Bh, where 8 represents the area of the base of the cylinder. Which expression can be used to find the value of B, in square centimeters, for this cylinder?

A (12.1 B 2(12.1)

C (3.8)

D None of these

Step-by-step explanation:

Given a cylinder with the following dimensions

Radius of the Cylinder =12.1 cm

Height of the Cylinder =3.8cm

Volume of a cylinder = Base Area X Height

The base area is a circle, therefore the expression that can be used to find the value of B, (in square centimeters), for this cylinder is given as:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
