Answer:
184.96
Step-by-step explanation:
V = (base × height) ÷ 3
base = pi × radius^2
2 × pi × radius = circumference
2×pi×r = 29.516
÷2 ÷2
pi×r = 14.758
÷3.14 ÷3.14
r=4.7
base= 3.14 × 4.7^2
= 69.36
V = (69.36 × 8) ÷ 3 = 184.96
Answer:
28
Step-by-step explanation:
60 apples by 5 is 12. When Georgia put some more apples in we now have to divide 60 by 3 which is 20 and then multiply that by 2 which is 40. So, if the ratio was 1:3 it would be 20:60 but it is 2:3 so the answer is 40:60. Do 40 minus 12 to find how much Georgia added. 40 minus 12 is 28.

Answer:
Slant height (s)= 12.1 cm
Step-by-step explanation:
Given: Base= 4.5 cm.
Surface area of right square pyramid= 129.5 cm.
First, calculating slant height (s) of right square pyramid.
Surface area of square pyramid= 
a= side of square base.
s= slant height
∴ 
⇒ 
⇒ 
Now, opening the parenthesis and subtracting both side by 20.25.
⇒
cross multiplying both side
∴ Slant height (s)= 12.1
