The radius of the base of the vase in cm is 8.26 cm
P = F / A
700 = 15 / A
Cross multiply
700 × A = 15
Divide both sides by 700
A = 15 / 700
Multiply by 10000 to express in cm²
A = (15 / 700) × 10000
A = 214.29 cm²
A = πr²
Divide both side by π
r² = A / π
Take the square root of both sides
r = √(A / π)
r = √(214.29 / 3.14)
r = 8.26 cm
