Answer:
Length=15cm
Hope this answer is right!!
Step-by-step explanation:
Length be 3 cm longer than the breadth.
So, x=y+3
Perimeter = 2(x+y)54
So, x+y=27 =>x=15
x-y=3 =>x=12
So, length is 15 cm
Answer:
B. 100 pi units squared
Step-by-step explanation:
Find the surface area of a sphere with radius 5 using the formula SA=4pir²
Leave answer in terms of π = pi
From the question
The formula for the Surface Area if a square = 4 × pi × r²
r = 5
Hence,
Surface Area of a Sphere = 4 × pi × 5²
= 100 pi units squared
Option B is the correct option
