Answer:
The answer is option 5.
Step-by-step explanation:
The formula is V = 1/3×π×r²×h where r represnt radius and h is height. Given that the diameter of cone is 8 inches so the radius is 4 inches then substitute the value into the formula :
Let r = 4,
Let h = 12,
P(7) = 57
Porque :
P(x) = x^2 + x + 1
P(7) = 7^2 + 7 + 1
P(7) = 49 + 7 + 1
P(7) = 57 ✔️
Answer:
x≥50
Step-by-step explanation:
The absolute value makes the -8 into a positive 8, then you subtract the 8 on both sides, giving you your answer 7. (Since 15-8=7)
Answer: 6.25
create a ratio of 2.5/2 = x/5 and solve for x. First multiple both sides by 10 so you get 12.5 = 2x. Then you get x = 6.25.
