Area of semicircle is given by:

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):

So, the area of this semicircle is
9.81m².
Answer:
Disagree, as m is common to all terms of the expression and thus, can be factored. The factored expression is 7m(2 + 3p - 5q)
Step-by-step explanation:
If a variable is common to all terms of an expression, it can be factored.
14m + 21pm - 35mq
Here, m is common to all terms of the expression, so the factored expression is:

Disagree, as m is common to all terms of the expression and thus, can be factored. The factored expression is 7m(2 + 3p - 5q)
Answer:
Solution is x = 8.
Step-by-step explanation:
2 is not a solution as √2*2 - 2 is not equal to -4.
