What is the approximate area of the circle shown below

Given: The figure of a circle with radius 21 cm².

To Find: Approximate area of the circle.

Solution: Answer is (B) 1385 cm².

Calculation/Explanation:

To find the area of a given circle, we must use the formula where r denotes the radius of the circle and assumes the usual value of 3.14 approximately.

We substitute the radius r = 21 cm² of the given circle into the equation above and simplify. Thus,

We round off to get approximately 1385 cm² which corresponds to answer B.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
