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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
