Answer:
1071.8 to 1 decimal point
Step-by-step explanation:
The first thing you would do is multiply the 4/3, 3.14 and the 8^3
So we know that 8^3 is 8X8X8 which is 512
So the first thing you do I 4/3 X 3.14 X 512 = 160768/75 (2143.6 1DP)
Then you would divide this by 2
2143.6/2 = 1071.8
Answer:
21cm^2
Step-by-step explanation:
V=B*h
B=(x-12)^2
h=6
(x-12)^2*6=486
Solve using quadratic equation and you get 21 and 3.
3 doesn't work so it is 21
Answer:
x = 2
Step-by-step explanation:
Given that the measure of segment BC must equal the addition of the measure of segment BA plus the measure of segment AC, we can write this in equation form:
BC = BA + AC
then we replace them with the measure information they provide:
12 x + 4 = 7 x - 4 + 8 x + 2
and we solve for x in the equation:
12 x + 4 = 15 x - 2
subtract 12 x from both sides:
4 = 15 x - 12 x - 2
4 = 3 x - 2
add 2 on both sides
4 + 2 = 3 x
6 = 3 x
x = 6/3
x = 2
Answer:
12
Step-by-step explanation:
N - 3 = 9
Add 3 on both sides,
N - 3 + 3 = 9 + 3
N = 12
Answer: Juan walks 246,176 yards around the circular path.
To find the distance around the circular path, we are looking for the circumference. The formula for the circumference is: C = pi(r^2).
Simply plug in the radius and evaluate the expression.
C = 3.14(280^2)
C = 3.14(78400)
C = 246,176 yd
