The radius of a circle is the distance from the center point of a circle to the outer edge of the circle. The diameter is the distance between one point on the outside of a circle and a point on the other side, and the diameter passes through the center point.

Therefore, the diameter is just twice the radius.

We know the radius is 3.5 cm, so we can just multiply:

3.5 * 2 = 7

The diameter of a circle with a radius of 3.5 cm is 7 cm.
Hope that helped! =)

4x+6 find find the value

Alex Ar [27]

Answer:

-1.5 or -6/4

Step-by-step explanation:

Im assuming the equation is 4x+6=0

1.) subtract the 6 from each side.

4x= -6

2.) you need to isolate the X, so divide the 4 from each side.

X= -6/4 or -1.5

A rectangle has a perimeter of 30 feet and an area of 50 square feet. What are the dimensions of the rectangle?

REY [17]

Perimeter (p) = 2×length (l) + 2×width (w)
p = 2l+2w
area (a) = l×w, so solve for one (I'll use l):
$a = l \times w \\ l = a \div w \\ p = 2l + 2w = 2(l + w)$
since p = 30, and a = 50, substitute the "a÷w" in for l in the perimeter equation:
$p = 2(l + w) = 2((a \div w) + w) \\ = 2((a \div w) + ( {w}^{2} \div w)) \\ p= 2((a + {w}^{2}) \div w$
Now plug in p and a values:
$p= 2((a + {w}^{2}) \div w) \\ 30 = 2((50 + {w}^{2}) \div w) \\ 30 \div 2 = (50 + {w}^{2}) \div w \\ 15w = 50 + {w}^{2}$
$15w = 50 + {w}^{2} \\ {w}^{2} - 15w + 50 = 0 \\ (w - 5)(w - 10) = 0$
therefore width can be either 5 or 10 (but not both), so let's plug in:
l = a÷w = 50÷5 = 10
So if w = 5, then l = 10

D) 5 feet, and 10 feet

A cylinder has a radius of 2x + 3 and height of 3x + 2. Which polynomial in standard form best describes the total volume of the

Bogdan [553]

Answer:

$v = \pi {r}^{2} h \\ v = \pi {(2x + 3)}^{2} (3x + 2) \\ v = \pi(4 {x}^{2} + 12x + 9)(3x + 2) \\ v =( 12 {x}^{3} + 36 {x}^{2} + 27x + 8 {x}^{2} + 24x + 18)\pi \\ v =( 12 {x}^{3} + 44 {x}^{2} + 51x + 18)\pi$
