V = 4/3πr^3V = 4/3 (π) (6.5)^3
V = 366.1666π (6 repeat)
answer is 366.16 π (3rd choice)
Answer:
30% of 150 is 45
Step-by-step explanation:
30% = .3 x 100
So take 30% out of its percentage form
then multiply .3 and 150
150 x 0.3 = 45
Henceforth, 30% of 150 is 45

Is there a picture or diagram or something
Given:
trap door = 130 square feet.
1st item: 6ft 5in wide & 8ft 9in long
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches
2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches
3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches
130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in
18,720 sq. in / 160 inches = 117 inches
Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
