Answer:
184.43in².
Step-by-step explanation:
Total surface area of the solid = volume of the cube - the volume of the cone
For the CUBE;
Volume of the cube = L³ where L is the length of one side of the cube.
Since a cone of diameter of 6in is cut into a cube, then the length of the cube will be 6in.
Volume of the cube = 6³ = 216in³
For the CONE;
Volume of the cone = 1/3 πr²h
r is the radius of the cone = diameter/2
r = 6/2 = 3in
slant height l = 4.5in
the height h of the cone will be derived using the Pythagoras theorem.
l² = h²+r²
4.5² = h²+3²
h² = 4.5²-3²
h² = 11.25
h=√11.25
h = 3.35in
Volume of the cone = 1/3 × π × 3²× 3.35
= 31.57in³
Total surface area of the solid = 216in³-31.57in³
= 184.43in²
Answer:
It would be 52
Step-by-step explanation:
You divide 91 by 7 and u get 13 so u multiply that by 4 and u get your answer
Ok so the formula for this is A=1/2bh lets plug it in.
A=1/2*16*8
A=8*8
A=64 in^2
Answer:
Step-by-step explanation:
To solve this, you need to find the unit price by dividing the cost by the amount. For Mike, divide $2 by 2 to get 1. So, Mike sells hot dogs for $1. Next, divide 2.25 by 3 to get $0.75. So, Sue sells hot dogs for $0.75.
Joe: $1.50
Mike: $1
Jen: $1.25
Sue: $0.75
So, the best deal is Sue because it is the cheapest per unit. Hope this helped!
