Answer:
300,000+100,000+7,000+80+1
Step-by-step explanation:
Yes they are equivalent. For the first one you reduce the second equation by 2. For the second pair you reduce the second equation by -3.
Step-by-step explanation:
20 x 399 x 5
= (20×5) × 399
= 100×399
= 39,900
Answer:
200π
Step-by-step explanation:
Surface area of a cone = πr(r+l)
r is the radius
l is the slant height
Volume of the cone = 1/3πr²h
320π = 1/3πr²h
320 = 1/3r²(15)
320 = 5r²
r² = 320/5
r² = 64
r = 8
l² = 15² + 8²
l² = 225 + 64
l² = 289
l = 17
Get the surface area;
S = πr(r+l)
S = π8(8+17)
S = π*8*25
S = 200π
Hence the surface area of the cone is 200π
I would be 1034 because if you do 6x94 it’s 564 so if you do 11x94 you get the total witch is 1034
