Answer: 18
Step-by-step explanation:
when there is a in front of an expression in parentheses change the sign of each term in the expression. 9+9=18 so ANSWER 18
Answer:
V = 65.19
Step-by-step explanation:
Remark
You need r. You can get it from the circumference of the circular base.
Once you have that, the formula is Area = 1/3 pi r^2 j
Givens
C = 20.236
h = 6 feet
Formulas
C = 2 pi r
Volume = 1/3 pi r^2 h
Solution
Find r from C = 2 pi r
20.236 = 2 * 3.14 * r Combine the right
20.236 = 6.28 * r Divide by 6.28
20.236/6.28 = 6.28 * r / 6.28
3.222 = r
Now that you have r, you can solve for the volume
V = (1/3) pi 3.222^2 * 6 Square r
V = 1/3 * pi * 10.381 * 6 Now multiply through by all, but pi
V = 20.762 pi
V = 65.194
Answer:
um heyz.
Step-by-step explanation:
please follow me and give me a thanks because im new user in brainly pleease and mark me as brainliest.
Any value that satisfies the equality.
E.g. 2x + 4x = 10 the value that makes this true is 2
or
x^2 = 2 The values that would make it true are 4 and -4, since the squared of any number is always a positive.
120+120=240
The roof of the house is 240 ft^2
