M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides
4 = r

CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4

Answer:

B. 33.7 mm; 54mm^2

Step-by-step explanation:

<em><u>To find the perimeter, use the formula:</u></em>

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

<em><u>To find area, use the formula:</u></em>

A = \frac{1}{2} bh

A = \frac{1}{2} (12)(9)

A = \frac{1}{2} (108)

A = 54

If the base of a square pyramid is 9 centimeters, and it has a volume of 324 cubic centimeters, what is the height of the pyrami
masha68 [24]

A

The volume (V) of a pyramid is found using the formula

V = \frac{1}{3} × area of base × height(h)

area of base = 9² = 81 ← area of a square, hence

324 = \frac{1}{3} × 81 × h = 27h ( divide both sides by 27 )

h = \frac{324}{27} = 12 → A
