Answer:
168 inches
Step-by-step explanation:
7 Feet = 84 Inches
84 + 84 = 168
1) c= 3.5cm × 22/7
c= 77cm/7 = 11cm
2) c= 2×3.14×5cm
= 6.28× 5cm
=31.4cm
3) L=180/360 × 22/7 × 3cm
= 1/2 × 22/7 ×3cm
=4.71 cm
4) c=12cm ×3.14
=37.68cm
5) c = 4.5cm × 3.14
=14.13cm
6) c = 6.7cm × 3.14
= 21.038cm
Answer:
40 feet
Step-by-step explanation:
The number of years since she moved in when she just moved in is 0,
thus, t=0
So,
H=3*0+40
H=40 feet
The height of the tree when Rebecca just moved in was 40 feet
