Answer:
13
Step-by-step explanation:
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
44% = 44/100 = 44 ÷ 100 = 0.44.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 44% of its value.
Percentage decrease = 44% × 13
New value = 13 - Percentage decrease
Answer:
rc length = 10 * 8pi/5
= 16pi
This is the circumference of the base
(a) 2pir = 16pi where r = radius of base
2r = 16
r = 8 cm
(b) 10^2 = h^2 + 8^2
h^2 = 100 - 64
= 36
h = 6 cm
You should divide 280 into 3 which would equal 9
