Taylor is making a cookie cake that has a diameter of 13 in. What is the area of a fourth of the cookie cake?

weqwewe [10]

Cookie Cake is in the form of a circle.

Radius of circle = 1/2 * diameter of circle = 1/2*13=13/2=6.5 in

Thus the Area of the circle = $\pi r^2$

= $\pi *6.5^2$

$= 132.73$

Area of a fourth of the Cookie cake $= \frac{1}{4} *132.73 = 33.18 in^2$

M∠LON = 7x-92 and m∠MON = 6x+12

Tomtit [17]

Answer:

$M∠LOM = \boxed{48}$

Step-by-step explanation:

$M∠LOM + m∠MON = 180 \\ 7x-92 + 6x+12 = 180 \\ 13x - 80 = 180 \\ 13x = 180 + 80 \\ 13x = 260 \\ \boxed{ x = 20} \\ (7x - 92 )= 140 - 92 = \boxed{48} \\$

Can you prove that DEF = HGF.!? Justify your answer.

frosja888 [35]

Step-by-step explanation:

$In \: \triangle DEF \: \& \: \triangle HGF \\ EF \: \cong \: GF...(given) \\ \angle EFD \cong \angle GFH \\ (vertically \: opposite \: angles) \\ \ DF \: \cong \: HF...(given) \\ \therefore \: \triangle DEF \cong \triangle HGF \\ (By\: SAS \:criterion\: of \:congruence)$
