Answer:
A
Step-by-step explanation:
To find surface area of a cylinder, find the 2 circles which is the formula a=pi(r)^2, when you get that, multiply that by 2 because both sides count. Than the middle which I would imagine like a soda can. Cut a line right down the middle and hen you take it out, it looks like a Rectangle. Find the circumvented of the circle which would be pi(d)=circumfrence. Now after that you found the top side now the other side is 12 as shown here on the model and multiply thm together you’ll get 84 pi. Now those 2 circles would add up to 32 pi. Add them together youll get 116 pi. Now pi could be any but I’d Use 3.14 which will get you about to A becuase after all 3.14 is an approximate.
There are 56 dogs
2/5 = x/140
140 x 2 = 5 x x
280 = 5x
56 = x
Answer: So Reina and Sam are multiplying (84)5 (73)9 and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's (84)5 (73)9 = 84-573-9 = 820727
So Sam's Actually they are doing or multiplying using exponents. Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.

The dimension of the rectangular box is 60cm x 45cm x 32cm. The dimension of the wood used has the thickness of 2.5 cm all around the rectangular box. In order to get the volume of the wood, subtract each side of the rectangular box by 2.5.
Volume = 57.5 cm x 52.5cm x 29.5cm
Volume = 89053.1252 cm^3
