Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A =
× 36 × 47 = 18 × 47 = 846 in²
Answer: 0.4 meters per hour.
Step-by-step explanation:
The rate of change of distance with respect to time is known as speed.
Formula :
Given : It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.8 meters.
i.e. Change in position= 2.8-2=0.8 meters
Change in time = 3-1=2 hours
i.e. 
Hence, the rate of change =0.4 meters per hour.
Answer:
the width is 15 and length is 25
Step-by-step explanation:
That is true because the square root of 32 is about 5.66, so 4.65 IS less than it.
Answer: 128.86cm²
Step-by-step explanation:
The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.
Area of the rectangle = 11 x 12
= 132cm²
Area of the circle with radius of 1cm = πr²
= 3.142 x 1²
= 3.142cm²
Therefore , area of the shaded region = 132cm² - 3.142cm²
= 128.86cm²
