Answer:
16π
Step-by-step explanation:
Area = πr²
r - radius
r = d/2 = 8/2 =4
Area = 4²π = 16π
11cm I think Someone help me with my question 2
Answer:
1
Step-by-step explanation:
4÷1=4 4×1=4 4+1 = 5 5-1 = 4
The answer
there is no more explanation about this question, the solution can be found easily by applying the rule of transformation of rotation
for example, the properties of rotation transformation are:
A rotation preserves length but does not necessarily preserveslope of a line.
A 90° rotation ( 1/4 turn) anticlockwise about the origin changesthe point (x; y) to (-y; x).
A 180° rotation ( 1/2 turn) clockwise or anticlockwise about theorigin changes the point (x; y) to (-x;-y).
A 270° rotation ( 3/4 turn) anticlockwise changes about the originthe point (x; y) to (y;-x).
so the answer is
<span>R0, 270°</span>
