Answer:
1385.622 cm^2
Step-by-step explanation:
The area of a circle is given by the formula
A = pi * r^2
We know the radius is 21 and pi is approximated by 3.142
A = 3.142 * 21^2
A = 3.142 *441
1385.622 cm^2
Answer:
Top Row:20,20
Bottom Row:26,26
Step-by-step explanation:
2(3m+7) when m is 1. Plug in to get: 2 (3*(1) + 7)=20
6m+14 when m is 1. Plug in to get: 6*(1) + 14=20
2(3m+7) when m is 2. Plug in to get: 2 (3*(2) + 7)=26
6m+14 when m is 2. Plug in to get: 6*(2) + 14=26
The person was incorrect because there are more sides than 6

Step-by-step explanation:
- write down the binary number; 110011
- multiply each digit of the binary number by the corresponding power of two: (1×2)5 + (1×2)4 +(0×2)2 +(0×2)2 + (1×2)1 +(1×2)0
- Solve the power: 1×32+1×16+0×8+0×4+1×2+1×1= 32+16+0+0+2+1
- Add up the numbers written above: 32+16+0+0+2+1= 51
So, 51 is the decimal equivalent of the binary number 110011.
