Answer:

25π/4 square meters

Step-by-step explanation:

The area of a circle is given by the formula ...

A = πr² . . . . . where r is the radius of the circle.

The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...

A = π(5/2 m)² = (25/4)π m²

The area of the circle is 25π/4 square meters.

As a decimal, that is 6.25π square meters.

Answer:

A = 6.25π

Step-by-step explanation:

Area of a circle:

A = πr²

Given:

d = 5

To find r, divide d by 2:

r = d/2

r = 5/2

r = 2.5

Area of a circle:

A = πr²

A = π2.5²

A = 6.25π

Paul and Jim work at a t-shirt factory. They pack t-shirts in boxes and send them

Gwar [14]

Answer:

Jim's box hold more t-shirts by 3 cubic feet

Step-by-step explanation:

Jim's box length = 2 feet

Jim's box breadth = 4 feet

Jim's box height = 6 feet

Volume of box = $Length \times Breadth \times Height = 2 \times 4 \times 6 = 48 feet^3$

Paul's box length = 3 feet

Paul's box breadth =5 feet

Paul's box height = 3 feet

Volume of box = $Length \times Breadth \times Height =3 \times 5 \times 3 = 45 feet^3$

So,Jim's box hold more t shirts by (48-45 = 3 cubic feet )

So, Option C is true

Jim's box hold more t-shirts by 3 cubic feet
