Answer:
The surface area is multiplied by 3.
Step-by-step explanation:
If r is the radius of a sphere its surface area = 4(pi)r^2. If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2. So the surface area becomes 4-fold or the increase in surface area is 300%.
7/4 * 301/2 (changed into mixed numbers)
2107/8
263.375
C
because when you change 3 into a mixed fraction its 263*8+3/8
263.375
#1
84 is divided into 7 84/7 =12
and it is added to
