Write an equation of the circle with center (6, 2) and radius 4.

luda_lava [24]

Answer:

$(x-6)^2+(y-2)^2=16$ .

Step-by-step explanation:

$(x-h)^2+(y-k)^2=r^2$ is the equation for a circle with center (h,k) and radius r.

You are given center (6,2) and radius 4.

So we will replace h with 6 and k with 2 and r with 4.

This gives us:

$(x-6)^2+(y-2)^2=4^2$

Simplify:

$(x-6)^2+(y-2)^2=16$ .

Find d and the measure of each side of equilateral triangle KLM if KL=d+2, LM=12-d, and KM=4d-13

fiasKO [112]

Answer:

all sides are 7 units

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are equal in length

equate any 2 sides and solve for d

KL = LM

d + 2 = 12 - d ( add d to both sides )

2d + 2 = 12 ( subtract 2 from both sides )

2d = 10 ( divide both sides by 2 )

d = 5

KL = d + 2 = 5 + 2 = 7

LM = 12 - d = 12 - 5 = 7

KM = 4d - 13 = (4 × 5) - 13 = 20 - 13 = 7

Use the net to find the lateral area of the cylinder. Give your answer in terms of pi.

MatroZZZ [7]

Answer:

$90\pi in^2$

Step-by-step explanation:

The lateral area of the cylinder is given by;

$A_L=2\pi rh$

The radius of the cylinder is $r=5in.$ and the height is $r=9in.$

Substitute the values to get;

$A_L=2\pi \times 5\times 9$

$A_L=90\pi in^2$
