Answer:
9π miles²
Step-by-step explanation:
The area of a circle is πr²
Now we plug in 3 miles for the radius
A=πr²
A=π3²
A=9π miles²
Answer:
20079.05 cm^2,
Step-by-step explanation:
Surface area of the box without the lid
= 90*42 + 2(90*34) + 2(42*34) = 12756.
Now find Surface area of the half cylinder:
The diameter of the 2 half circles = 42 so the radius = 21.
The area of the lid
= 2 + 1/2 π (21)^2 + π r * 90
= 7323,052
Total = 20079.052
A) Mr Chen was worth:
45,000/5 = 9,000
9,000 x 100 = 900,000
The answer is 900,00

Answer:
I can only read the top 2 dimensions:
The one on the left is 32 ft^2, the one on the right is 31 ft^2
Step-by-step explanation:
left top: (8x5)-(2x4) = 32
right top: (8x4)-(1x1) = 31
left low: (10x?)-(4x7) = ?
right low: (8x?)-(2x6) = ?
