If the diameter of the circle above is 20 mm, what is the area of the circle? A. 100 mm2 B. 400 mm2 C. 20 mm2 D. 10 mm2

The answer is 100π.

Step-by-step explanation:

Since the diameter of the circle is 20mm, the radius of the circle is 20/2 = 10mm.

The formula for area of a circle is π*r^2. If we substitute r for 10, we get the final answer as 100π or about 314.16.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
