Answer:
90π yd²
Step-by-step explanation:
the surface area of a cylinder is the sum of the lateral area and twice the aera of one end of the cylinder: π·d·l, where l represents the length of the cylinder. Here, the lateral surface area is π·6 yd·12 yd, or 72π yd².
The two ends add the following to the total surface area:
2·π·(d/2)², or 2π·d²/4.
Thus, the total surface area of the cyl. is
A = 2π·(6 yd)²/4 + 72π yd², or
A = 18π yd² + 72π yd² = 90π yd²
Note: Please check your source. L x W + 2pi ·r ^2 is incorrect.
The answer is D (42.39 cubic inches)
Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is 
. We can rearrange that to get: 
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
948 divided by 1,000 is 0.948
Answer:
A = 
yd²
Step-by-step explanation:
the area ( A) of a rectangle is calculated as
A = length × width
= 
× 
= 
= yd²
