15+22(4+11)=x
4+11=15
22*15=330
15+330=345
x=345
Answer:
Circumference is 2piR =31.4
Area is pir^2=78.5
Step-by-step explanation:
Answer:
The lateral surface is 120 , which agrees with the third answer option of the list.
Step-by-step explanation:
Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.
Then the lateral area of the prism is:
Lateral area= 5 (6" x 4") = 5 (24) = 120
1 L = 1000 mL
1 kg = 1000 g
You can use this to convert the equations.
200 mL of paint x 5 = 1000 mL (1 liter)
40 g x 5 = 200 grams of paint powder
200 g x 20 = 4000g of paint powder for 20 liters of paint
4000g/600g = 6 2/3
You’ll need 7 packets of paint powder.
