Answer:
186.45 cm^3
Step-by-step explanation:
Given data
Side lenght of cube block= 8cm
Radius of cylindrical hole= 3.6cm
Volume of entire Shape= l^3
Volume of entire Shape= 8*8*8
Volume of entire block= 512cm^3
Volume of cylindrical hole= πr^2h
Volume of cylindrical hole= 3.14*3.6^2*8
Volume of cylindrical hole= 3.14*12.96*8
Volume of cylindrical hole= 325.55cm^3
Hence the volume of the block
=volume of entire shape- volume of cylinder
=512-325.55
=186.45 cm^3
Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α

Step-by-step explanation:
answer:
a. scarf costs today = $6
b. scarf costs 3 days from now = $3
step-by-step explanation:
- 1/2 off means you would multiply the amount by 1/2 then subtract
a. original price of scarf: $12
12 X 1/2 = 6
12 - 6 = 6
— scarf costs today = $6
- do the same thing but this time it is a different number
b. 12 X 3/4 = 9
12 - 9 = 3
— scarf costs 3 days from now = $3
