Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
Thirteen plus seven is twenty. One fourth of twenty is five.
The answer is five.
Step-by-step explanation:
If 200 g fertiliser required for 8 m^2 then for 1m^2 we'd need 25 g of fertiliser
(i) 14×25 = 350 g fertiliser would be needed for 14 m^2 land
(ii) 450÷25 = 18 m^2 land could be fertilised with 450 g fertiliser
