Question

draw to construct circle of radius 3 cm and 5 cm construct a tangent to smaller circle from a point on the large circle also measure its length
​

Answer 1

Answer:

4cm

Step-by-step explanation:

A tangent to a circle is perpendicular to the radius at the point of tangency.

Using this property and Pythagoras Theorem,

${AO}^{2} = {AP}^{2} + {OP}^{2} {5}^{2} = {AP}^{2} + {4}^{2}$

Thus, AP=4 cm
