Answer: D

Step-by-step explanation:

Remember the formula -

$A = \pi$ × $r^{2}$

π = 3.14

$r^{2}$ = 7

7² = 49

3.14 x 49 = 153.94

A = π · r² = π · 72 ≈ 153.93804

153.93804 ⇒ 154 (rounded)

Your answer is D.

Step-by-step explanation:

So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below
