Answer:
The volume is 908 feet³
after rounding it is 900 feet³
Step-by-step explanation:
Radius of cone from fig. A = 2feet
Radius of cylinder from fig. B = 2feet
Radius of Hemisphere from fig. C = 3feet
Height of cone from Fig. A = 6 feet
Height of cylinder from fig. B = 10 feet
Length of cuboid = 12 feet
height of cuboid = 4feet
width of cuboid = 7feet !!

⤻ Before solving the given question , you should know the answer of these questions :
✺How do you find the hypotenuse , perpendicular and base when the angle ( ) is given ?
⇾ The longest side , which is the opposite side of right angle is the hypotenuse ( h ). There are two other sides , the opposite and the adjacent. The naming of these sides depends upon which angle is involved. The opposite is the side opposite the angle involved and it is called the perpendicular ( p ) . The adjacent us the side next to the angle involved ( buy not the hypotenuse ) and it is called the base ( b ).
☄
In the above cases , is taken as the angle of reference.
♪ Our Q/A part ends up here! Let's start solving the question :
❈
- Perpendicular ( p ) = ? , Hypotenuse ( h ) = 18 & base ( b ) = 16
✧
- Value of tan
✎
Firstly , Finding the value of perpendicular ( p ) using Pythagoras theorem :
❃ [ Pythagoras theorem ]
Okey, We found out the perpendicular i.e . Now , We know :

Answer:
The expression that is greater is a (b - c)
Step-by-step explanation:
- a < 0 and c > b, this means <u>(by the addition property)</u> that c - c > b - c⇒0 > b - c
so for the product <u>a(b - c) </u>we would have a multiplication of a negative number <em>a</em> and another negative number <em>(b - c)</em>. We know that the result of the <u>multiplication of two negative numbers is a positive number.</u>
Therefore, a (b - c) > 0
- a < 0 and c > b, this means <u>by the addition property</u> that c - b > b - b⇒ c - b > 0
so for <u>a(c - b)</u>, we have the negative number <em>a</em> multiplied by the positive number <em>(c - b). </em>We know that the result of the <u>multiplication of a negative number by a positive number is negative. </u>
<u>Therefore a (c - b) < 0</u>
Thus, the expression that is greater is the positive one which is a (b - c)
