Calculate the area of a circle with diameter of 10cm

Mathematics
1 answer:
Annette [7]4 years ago
7 0

The area of ANY circle is (pi) x (radius)² .

The radius of a circle is (1/2) x (the diameter).
So for your circle, the radius is (1/2) x (10cm) = 5 cm.

Write that in place of 'radius' in the formula, and use 
3.14  for 'pi', and the answer will jump out at you.

the local hardware store wants to increase their inventory. Last year 15 electric screwdrivers cost them 300.how much would 45 s
Harman [31]
One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x).    Solve this equation for x.  To do this, you might try multiplying both sides of this equation by x to eliminate fractions.

Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.
