Answer:
S.A. = 15.7
Step-by-step explanation:
S. A. = 
1 x 1 x 3.14 = 3.14
3.14 x 1 x 4 = 12.56
12.56 + 3.14 = 15.7
Answer:
If I've done it right the answer should be A, the figures are congruent because a 270 rotation about the origin a d a reflection of the x-axis
This is the answer and the steps for doing it
Answer:
408.46cm^2
Step-by-step explanation:
Given data
Height= 13cm
Diameter= 10cm
Radius= D/2= 10/2= 5cm
The area of the curved surface will be = 2πr × h = 2πrh
substitute
Area of the curved surface = 2πrh= 2*3.142*5*13
Area of the curved surface = 2πrh= 408.46cm^2
Hence the area of the curve surface is 408.46cm^2
