Answer:
V = 4/3 x pi x r^3
972 x pi= 4/3 x pi x r^3
729 = r^3
The cubic root of 729 is 9 because 9 x 9 x 9 = 729.
The radius is 9 inches, and the diameter is 18 inches.
The volume of the box is 18 in x 18 in x 18 in or 5832 in.³.
Step-by-step explanation:
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
Answer:
25%
Step-by-step explanation:
The tip percentage is 100 times the ratio of what you tipped to what you paid.
100 x (1 dollar tip) / (4 dollars paid) = 25%
Answer:
y = 8 or y = -14
Step-by-step explanation:
Solve for y over the real numbers:
abs(y + 3) - 4 = 7
Add 4 to both sides:
abs(y + 3) = 11
Split the equation into two possible cases:
y + 3 = 11 or y + 3 = -11
Subtract 3 from both sides:
y = 8 or y + 3 = -11
Subtract 3 from both sides:
Answer: y = 8 or y = -14
