Cool I don’t know what to say
<h3>Radius = 14cm</h3>
Step-by-step explanation:
Let O be the centre of the circle. Since P and S are the points of contact of tangents AD and DC respectively, OP ⊥ AD and OS ⊥ DC
Also, AD ⊥ DC (given), therefore, OPDS is a square.
BR = BQ = 27cm...(tangents from an external point to a circle are equal in length)
therefore, CR = CB - BR = (38 - 27)cm = 11cm
SC = CR = 11 cm...(tangents from an external point) therefore, DS = DC - SC = (25 - 11) cm = 14 cm.
therefore,
Radius of a circle = OP = DS = 14 cm...(therefore, OPDS is a square).

Answer:
120 degrees.
Step-by-step explanation:
The 5 exterior angles sum to 360 degrees.
So the 5th exterior angle = 360 - 4(60)
= 360 - 240
= 120 degrees.
As seen, the graph is pointing/increasing upwards. This means that the graph is exponentially increasing.
You notice there are significantly more spores at 4th hour than the first, therefore, this is an increasing trend.
Hope I helped :)
Not 100% sure this is right but
60cm^2
