Answer:
1 pi: 3pi
Step-by-step explanation:
Step 1: Formula of surface area and volume of sphere
Surface area of sphere = 4 x pi x r^2
Volume of sphere = <u>4</u> x pi x r^3
3
Step 2: Apply values in the formula
r = radius
radius = diameter/2
r=18/2 = 9
S.A = 4 x pi x 9^2
S.A = 324pi
Volume = <u>4</u> x pi x 9^3
3
Volume = 972pi
Step 3 : Show in ratio
Surface area : Volume
324pi : 972pi
= 1 pi: 3pi
Answer:
x and EAF are 27 degrees
Step-by-step explanation:
Since GAF is a right angle as indicated by the little square, GAC and CAF must add up to 90 degrees. Therefore, x is 90-63=27 degrees. The situation is the same for angle EAF. Hope this helps!
Answer:
25 dogs and 55 cats
Step-by-step explanation:
5/11 ratio, first add those up which you get 16
Then divide the total amount of animals by the ratio-80
80/16 = 5
(5*5)/(11*5)
25 dogs and 55 cats
Replace the x in -3^x by 1
Answer is -3^1 = -3
