Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
Hope it helps!
Answer:
Given - A rectangle whose area is 1 2/5 m^2
- length is 4/5 m
To find - Length of rectangle
Solution -
1 2/5 = 7/5 m^2
Let the length be X
Area of rectangle= Length × Breadth
7/5 = X × 4/5
7/5 × 5/4 = X
7/4 = X
Length of rectangle= 7/4
× equals negative 4 i think and y equals -3
