This was my answer for someone else question exactly like this :)
Answer:
Volume of composite is 483
Step-by-step explanation:
We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):
Volume of the prism = 7 x 12 x 3
= 252
Volume of the semi-cylinder = 
Therefore the sum of both volumes gives:
(252 + 230.907)
= 482.907
WHich can be rounded to the nearest whole number as: 483
Answer:
y=-1x+8
Step-by-step explanation:
idk what to do here
Answer:
solution: x = -8
Step by step:
1) 5x-5+5 = -45+5 : Add 5 to both sides
2) 5x= -40 : Simplify
3) 5x/5 = -40/5 : Divide both sides
Hope that helps
Answer:
104.8cm³(1 decimal place)
Step-by-step explanation:
Volume of a cone is given by the formula
V=1/3πr²h
we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7
V=1/3× 22/7×5²×4
V=1/3 × 22/7 ×25 ×4
V=2200/21
V=104.76190476
V=104.8cm³(1decimal place)
