The answer is

steps
#1) Try to leave a by itself by dividing any variable next to it

you can only divided these variables as all these variables in the original equation. are being multiplied. The opposite if multiplication is division.
complementary angles sum up to 90°.
so if one of them is 43°, then the other is just 90 - 43 = 47°.

28.26
Step-by-step explanation:
To find the area of a circle you take pi times the radius squared (
)
And to find the radius you divide the diameter by two.
Answer:
298 cm^2.
Step-by-step explanation:
There are 3 pairs of faces of equal area.
Area of top = 7 * 11. So it's 2 * 7 * 11 = 154.
Area of a smaller side = 7 * 4 so we have 2*28 = 56 .
Area of larger side = 4*11 so it's 2*44 = 88.
Total surface area = 154 + 56 + 88
= 298.
