Both circle q and circle r have a central angle measuring 110°. the area of circle q's sector is 4π cm2, and the area of circle r's sector is 9π cm2. the radius of circle q is 7 cm. which is the radius of circle r

The area of circle Q's sector = 4π

the area of circle R's sector = 9π

The radius of circle Q = 7 cm

We need to find the radius of circle R that is x

Given : Both circle Q and circle R have a central angle measuring 110°

So the radius of circle R to the radius of circle Q is equal to the square root (area of circle R to the radius of circle Q)

Plug in all the values

Therefore , the radius of circle R = 10.5 cm

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for
