Hey there!
Sorry If this answer is late, but here ya go.
To find the radius of this Brazilian coin, first multiply 3.14 by 2. This will give you and answer of 6.28. Then, divide 84.78 mm by this, and you will get your radius of 13.5.
Have a good day! And stay CRAZZZY! :D
Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.

Answer:
42
Step-by-step explanation:
Break the trapezoid into three shapes; two 4*3 triangles and one 4/5 rectangle. sole the area for each of the individual shapes and add them all together.
12 + 12 + 20 = 42
To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66
The calculation for surface area is <span>A = 4πr^2.
</span>A = 4<span>π(3.66)^2
Solve for A.
A= 168 cm^2.</span>
