Answer: 198cm
Step-by-step explanation:
We are given the dimensions of a rectangular prism;
3cm 9cm and 6cm
We are required to determine its surface area;
We need to know that;
Surface area of a rectangular prism is given by;
A = 2(WL+HL+WH)
Where L, W and H are length , width and height respectively;
Assuming;
Width is 3 cm
Length is 9 cm, and
Height is 6 cm
Then;
Area = 2 ( (3×9) + (6×9) + (3×6))
= 2(99)
= 198 cm²
Therefore, the area of the rectangular prism is 198 cm²
Yes, you are correct. Suppose the relationship is p=aq. Put p=10 and q=2 in, we can get p=5q. So when q=20, p=20*5=100. So the answer is D. Be confident with yourself~
Answer:
45 degrees
Step-by-step explanation:
45 is half of 90, 90 is a right angle
Answer:
x= -9/5, y= 34/5
Step-by-step explanation:
:) hope you get it right!~
The kite forms a right angled triangle with hypotenuse of 50 ft. The height of the kite above the ground is the opposite of 60° angle.
Using the sine rule,
Sin 60 = Height of the kite above the ground/Hypotenuse
Therefore,
Height of the kite above the ground = Hypotenuse*Sin 60 = 50 *Sin 60 = 43.3 ft
