A vase with a circular base exerts a force of 15 N on a table with a pressure of 700 N/m2. Find the radius of the base of the vase in cm to 2 dp.

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
