For x=1
h(2)=h(1)+h(0)
h(2)=12+3
h(2)=15
for x=2
h(3)=h(2)+h(1)
h(3)=15+12
h(3)=27
for x=0
h(1)=h(0)+h(-1)
12=3+h(-1)
h(-1)=12-3
h(-1)=9

Step-by-step explanation:
Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
