Answer:
r = 5 cm
Step-by-step explanation:
A = πr²
78.53 = (3.14)r²
divide by 3.14
25 = r²
r = ±5
r = 5
415 is estimated to 420 because 415 surpassed 410 already or you around the one up from the tens place.
Answer:
Step-by-step explanation:
Step 1
Find the value of x
we know that
In an inscribed quadrilateral the opposites angles are supplementary
so
In this problem
substitute the values and solve for x
step 2
Find the measure of angle B
substitute the value of x
M < EFG = m < QFG is needed
Answer: x - 5
Step-by-step explanation:
Since, the area of the rectangle =
Length of the rectangle = x+5
Let the width of the rectangle = b
Thus, the area of the rectangle =
⇒
⇒
⇒
Therefore, the expression that shows the width of the rectangle = x-5
