I am almost positive that it is A. Because the lines mean absolute value so that would change the negative numbers to positive. And since there is not a line under the less than sign 4 can not be in the answer.
To find the difference between two numbers, subtract.
405.87 - 379.5 = <span>26.37</span>
Answer:
31792.5 cu
A cylindrical tank has a radius of 15 feet and a height of 45 feet. Volume of cylinder = pi *r^2*h , volume =3.14*15^2*45 , volume = 31792.5 cu.
so the answer is B

Answer:
Step-by-step explanation:
The area to be resurfaced is the area of the
whole circle including garden and lanes minus
the area of the garden.
Area of a circle is (pi)r2
radius of garden is (1/2)diameter = 8 m
Garden area: (pi)82 = 64(pi) m2
Diameter of garden plus traffic lanes is
16 + 2(6) because we add 6 m to both sides
of the diameter of the garden.
Full diameter = 16+12 = 28 m
Full radius = 28/2 = 14 m
Full area: (pi)142 = 196(pi) m2
Area to be resurfaced:
196(pi) - 64(pi) = 132(pi) m2 ≅ 415 m2
