Asemicircular flower bed has a diameter of 3 metres.
what is the area of the flower bed?
m2

give your answer to 1 decimal place.

area of circle = πr²

use π = 3.14

you can use a calculator for this question.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
