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.
Answer:
Step-by-step explanation:
1/3 is 0.3333333 and you round it by the 3rd three, so it looks like 0.334
Answer:
Step-by-step explanation:
The angles between the parallel sides add up to 180 degrees.
So 180-70 = 110 degrees.
1. The number 3 is located in the hundred thousands place.
2. Since the number 4 is located in the ten thousands place, it's telling 3 to stay the same
Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...
342,802 ⇒ 300,000
