The circle area formula is A=pi r^2. I am assuming those numbers represent diameter, and diameter is radius x 2. 6/2=3, and pi 3^2= 28.27433388. Divide this by 2 and the area of your half circle is 14.13716694. On the other half circle, 5/2= 2.5. pi times 2.5^2 is 19.63495408, divided by two is 9.817477042. Hope it helps!

What is the length of JK¯¯¯¯¯, to the nearest tenth of a millimeter? 4.5 mm 5.6 mm 8.3 mm 19.9 mm A horizontally-aligned scalene
Leokris [45]

Answer:

5 = side a

3 = side c

angle B = 62 degrees

JK is side b

Use the Law of Cosines to find the length of side b.

b^2 = a^2 + c^2 − 2ac cos(B)

b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)

b^2 = (25 + 9) − 30 x 0.469

b^2 = 34 - 30 x 0.469

b^2 = 34 - 14.084

b^2 = 19.916

b = √19.916

b = 4.463

Rounded to the nearest tenth is 4.5 mm.

Hope this helps!
