The radius of the new sphere is 9
The new SA should be 1017.36 in
New volume should be 3052.08in^3
x = 14
Explanation:
height = x
base 1 = 98
base 2 = 2
Using altitude formula in geometric mean:
base 1/height = height/base 2
98/x = x/2
![\begin{gathered} 196=x^2 \\ \text{square root both sides:} \\ \sqrt[]{196}\text{ = }\sqrt[]{x^2} \\ x\text{ = }\sqrt[]{196} \\ x\text{ = 14} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20196%3Dx%5E2%20%5C%5C%20%5Ctext%7Bsquare%20root%20both%20sides%3A%7D%20%5C%5C%20%5Csqrt%5B%5D%7B196%7D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7Bx%5E2%7D%20%5C%5C%20x%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B196%7D%20%5C%5C%20x%5Ctext%7B%20%3D%2014%7D%20%5Cend%7Bgathered%7D)

Answer:
29.3
Step-by-step explanation:
to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.
first we have to find the sum of the minutes she practiced:
20+30+40+38+25+22+39+22+26+31
this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:
293/10 =29.3
