The working out would be-
Pi x radiussquared
Pi x 64 = 201.0619298297468
Rounded to 2 decimal places =
201.06 feet2
Answer:
75°
Step-by-step explanation:
∠DGF = 2* ∠DEF
10x + 50 = 2(9x - 15)
10x + 50 = 18x - 30
50 = 18x - 30 - 10x
50 = 8x - 30
8x - 30 = 50
8x = 50+30
8x = 80
x = 80/8
x = 10
∠DEF = 9x - 15
= 9*10 -15
= 90 - 15
= 75°
Answer:
{-8, 8}
Step-by-step explanation:
Simplify 7· |n| = 56 by dividing both sides by 7:
|n| = 8
Because this is an absolute value equation, there are two separate solutions. One is n = +8 and the other is n = -8.
