Answer:
we cant just tell that. we need numbers. and problems.
Step-by-step explanation:
Well to isolate the variable you should subtract 6 from both sides resulting in -4y > 16
Now just divide by -4, however, keep in mind that when you divide or multiply by a negative number when there is a sign, always switch the sign, so just divide by -4 and get y < 4
Answer:
vol = 62 in³
Step-by-step explanation:
First determine r (see attached image) by using pythagorean theorem.
a² = b² + c²
a = 3 in
b = 3/2 = 1.5 in
c = r
3² = 1.5² + r²
r =
r = 2.598 in
Get the area = n/2 * a * r
n = number of sides = 6
r = 2.598 in
Area = 6/2 * 3 * 2.598
Area = 23.38 in²
get the volume = 1/3 * Area * h
Area = 23.38 in²
h = 8 in (as given)
vol = 1/3 * 23.38 * 8
vol = 62 in³
Answer:
area of the circle = 490.625 unit²
Step-by-step explanation:
The circle is inscribed into the square ABCD . The picture illustrate a circle inscribed in a square. All the sides of a square is equal. The angles are also equal.
area of a square = L²
area of the square = 625
625 = L²
square root both sides
L = √625
L = 25
The length of each sides of the square = 25
Area of the circle = πr²
where
r = 25/2 = 12.5
area = π × 12.5²
area = 156.25π
area = 156.25 × 3.14
area of the circle = 490.625 unit²
