Answer: 6.5 ft³
Step-by-step explanation:
P =4l => l = 7.3/4 = 1.825 ≈ 1.8 ft
V = Ab×h/3 = l²×h/3
= (1.8)²×6/3
= 3.24×2
= 6.48 ft³
≈ 6.5 ft³
The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm
This is not possible. A triangle is either acute (all angles less than 90 degrees), right (one 90 degree angle), or obtuse (an angle with more than 90 degrees). There can not be an "acute right triangle."
Answer:
i think the answer is 8
Step-by-step explanation:
"three less than the quotient of 6 and a number (n=3) increased by nine"
(6÷3)-3+9
the quotient of 6 and 3 (6÷3) is 2
three less than 2: 2-3 which equals -1
increased by nine: -1+9 (which is also the same as 9-1) is 8
please don't hesitate to ask for clarification! hope i helped!
