The surface area is 47.1 sq in.
Step-by-step explanation:
Given,
The height (h) of the coin (cylinder shaped) = 5 inches
The radius (r) = 1.5 inches
To find the surface area of the coin.
We need to find the lateral surface area of the coin.
Formula
The surface area of the coin of radius r and height h is 2πrh.
Now,
Putting the value of h and r and π=3.14 we get,
Area = 2×3.14×1.5×5 sq inches
= 47.1 sq in
Hence, the surface area is 47.1 sq in.
It would be 32-4x=12
32-4(5)=12
32-20=12
12=12
Answer:
27.7 (rounded)
Step-by-step explanation:
Answer:
208 or 26(8)
Step-by-step explanation:
8*26=208
26*8=208
Around 4.5π. This can be determined by the volume of a sphere formula.
