Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D
That would be ten factorial, 10!, or 10*9*8*7*6*5*4*3*2*1, which would be 3628800
Answer:
1.134
Steps:
= (4.51 - 5.32)(5.17-6.57)
= -0.81 × (-1.4)
= 1.134
Answer: 
Step-by-step explanation:
We need -9x on the left side, to move it, we must add 9x on both sides.
Done. We have Ax = 9x, By = 1y and C after the equal sign = -6
