What is the area of a semicircle of a diameter Cm?
The area of a semicircle can be calculated using the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. Since the diameter is given as ( Cm ), the radius ( r ) is ( \frac{Cm}{2} ). Plugging this into the formula gives ( A = \frac{1}{2} \pi \left(\frac{Cm}{2}\right)^2 = \frac{\pi (Cm)^2}{8} ). Thus, the area of the semicircle is ( \frac{\pi (Cm)^2}{8} ).

What is the semi circle radius 10cm?
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
The area of the semicircle is increasing at a rate of 1 cm2sec when the radius of the semicircle is 3cm?
To find the rate at which the radius is increasing when the radius is 3 cm, we use the formula for the area of a semicircle, ( A = \frac{1}{2} \pi r^2 ). Differentiating with respect to time, we have ( \frac{dA}{dt} = \pi r \frac{dr}{dt} ). Given ( \frac{dA}{dt} = 1 ) cm²/sec and ( r = 3 ) cm, we can substitute to find ( 1 = \pi (3) \frac{dr}{dt} ), leading to ( \frac{dr}{dt} = \frac{1}{3\pi} ) cm/sec. Thus, the radius is increasing at a rate of approximately 0.106 cm/sec when the radius is 3 cm.
