Answer:
C. 314 units2
Step-by-step explanation:
Sphere Formula:
SA=4πr²
SA= 4×3.14×5²= 314 units2
Use the formula for the slope of a line by substituting the given coordinates:

So for the coordinates (2,22) and (-4,-32)
So (-32-22)/(-4-2)= -54/-6= 9 is the slope of the line
You multiply fractions simply by multiplying numerators and denominators with each other:


The Angle formed by an arc on the centre of the circle is double the angle made by the same arc on the circumference of the circle.
So,

Answer:
2: 27.679
3: 11.887
4: 27.679
5: 35.46
6: 27.698
Step-by-step explanation:
2: you just have to add 22.89 + 4.789
3: here you just have to subtract 13.87 - 1.983
4: here you have to multiply 22.17(4.1)
5: here you have to divide 28.368 ÷ 0.8
6: here you have to divide 664.752 ÷ 24
