What is the approximate area of the circle shown below? (The radius is 21cm) A. 1385 cm2
B. 66 cm2
C. 5540 cm2
D. 132 cm

The answer is A. 1385 cm2

Step-by-step explanation:

Use the formula A = pi times radius squared

A. 1385 cm²

Step-by-step explanation:

Area of a circle is πr²

We know what the radius is, so all we have to do is plug it in.

π(21)²

π(21)²= 1385.44

Since it's approximate, it would just be 1385 cm²

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
