And
consecutive angles have sum 180°
- 7y+3+86=180
- 7y+89=180
- 7y=91
- y=13
So
- 5z+4+86=180
- 5z=180-90
- 5z=90
- z=14

Step-by-step explanation:
A
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then
A = π × 6² = 3.14 × 36 = 113.04 m²
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 28.26 , then
2πr = 28.26 ( divide both sides by 2π )
r = = = 4.5 in
Answer:
13
Step-by-step explanation:
Evaluate 3² then add and subtract, that is
10 + 3² - 6
= 10 + 9 - 6
= 19 - 6
= 13
Do the following,
(18x2)x2=?
(18x9)x2=?
(9x2)x2=?
Then add them all up!
