The diameter is twice as big as the radius
D=228
when 2 numbers or variables are next to eachother it means you need to multiply. So in this case r=57 and t=4 and we mulitply. 57 x 4 = 228. So the answer is 228. Hope this helps and have a great day!
Answer:
The Formula is 4 x Pi x Radius Squared . surface area of sphere = 4 x pi x radius x radius where "x" indicates multiplication and pi = approximately 3.141592654 4 * pi * r^2
Step-by-step explanation:
Answer:
2b+t/2=a
Step-by-step explanation:
3a + 4b = 5a-t
-3a -3a
4b = 2a - t
+t +t
4b + t = 2a
/2 /2
2b+t/2=a
Z-4/9-1/3=5/9
z-4 =5/9(9-1/3)
z-4 =4.414814815
z =8.814
