m = - 1 / 2
I am not really sure but I have a feeling it’s (B.)
Answer:
yes!
Step-by-step explanation: im pretty sure it is
Volume of a sphere can be found by using the formula V=
where r is the radius of sphere.
Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written
and need to find what should be multiplied in numerator with pi.

As r= 7 she needs to multiply numerator 
The number to be multiplied is 1372.
Step-by-step explanation:
By AAS congruence, triangles RNM and RNP are congruent. Hence 7x = 2x + 25, x = 5.
Line RM = 7x = 7(5) = 35 units.
