The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.
sq. cm.
Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is
sq. cm.
Then the total surface area is:
sq. cm.
Answer: 119.7 sq. cm.
Answer:
201.1 km^3
Step-by-step explanation:
The volume of a cylinder is V=πr2h. In this problem, our radius is 8, and our heigh is 4. Plugging in our values we get:
V=π(8)(2)(4)=64π, which is approximately 201.1.

Answer:
5/8 is smaller.
Step-by-step explanation:
A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777
Then to compare them you see which is smaller or bigger.
0.77777 is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.
13+3k=11
-Move constant to the right-hand side and change its sign
3k=11-13
Calculate the difference
3k=-2
Divide both sides by 3
K= -2/3
Answer:
48y
Step-by-step explanation:
Use the distributive property:
31y +17y = (31 +17)y = 48y
