3 9/10 + 4/5
39/10 + 4/5
39/10 + 8/10
47/10= 4 7/10
Yes
8+3= 11
You regroup the one
4+2=6+1=7
Hope this helps!
Answer:
f= -15
Step-by-step explanation:
u just have to divide
-75/5= -15 so f equal -15
-9-(-12)=-9+12=3
-9-12=-9+(-12)=-21
Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:
Surface area = 6 × a2
Right circular cylinder:
Surface area = 2 × pi × r2 + 2 × pi × r × h
pi = 3.14
h is the height
r is the radius
Rectangular prism:
Surface area = 2 × l × w + 2 × l × h + 2 × w × h
l is the length
w is the width
h is the height
Sphere:
Surface area = 4 × pi × r2
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r2 + pi × r ×( √(h2 + r2))
pi = 3.14
r is the radius
h is the height
l is the slant height
Right square pyramid:
Surface area = s2 + 2 × s × l
s is the length of the base
h is the height
l is the slant height
