the radius of a circle is 15 cm what is the area of a sector having an arc measure of 56
10^20/10^-19
2.2*2.2 = 4.84
find the area of triangle ABC, given two sides and their included angle :
a=200,b=120, gama=150
rearrange x/y = p/q to make y the subject
x^2 - 4x = 0
find 3√27+3√0.008+3√0.064
2xdx/x+3
2,2*2,2
