The ones with a square in a picture is a 90 degree angle the rest are a 180
Answer:
558
Step-by-step explanation:
(93) 6 =?
Bracket is treated as of or multiplication
(93)*6 = 558
A=115 and C=50.
because sum of all angles should be 180. so the x would be 32 and. ...
Answer:
The diameter will increase at a rate of 1/30π cm/min
Step-by-step explanation:
Here we want to calculate the rate at which the diameter will increase
Mathematically, the area of a sphere is given as;
A = 4πr^2
But r = d/2
so A = 4 * π * d/2 * d/2 = πd^2
dA/d(d) = 2πd
Thus dd/dA = 1/2πd = 1/2 * π * 15 = 1/30π
Given dA/dt = 10
Mathematically;
d(d)/dt = d(d)/dA * dA/dt
dd/dt = 1/30π * 10 = 10/30π = 1/3π cm/min
