Answer:
Exact area: 39.2π cm²
Approximate area: 123.2 cm²
Step-by-step explanation:
The area of a circle is πr².
A full circle can be thought of as a sector of a circle with 360° of central angle. For a sector of a circle with a central angle of n°, multiply the area of the circle by the fraction n°/360°.
The formula for the area of a sector of circle with central angle n° and radius r is
A = (n°)/(360°) × πr²
Here we have n = 72; r = 14 cm
A = (n°)/(360°) × πr²
A = (72°)/(360°) × π × (14 cm)²
A = 39.2π cm² = 123.2 cm²

Answer:
Dijonea have 8192 megabytes on her memory card
Step-by-step explanation:
Capacity of Tammy's memory card = 4-gigabyte
given that Dijonea buys a memory card with twice as much storage as Tammy’s
Thus,
Capacity of Dijonea's memory card = 2*Capacity of Tammy's memory card
Capacity of Dijonea's memory card = 2*4-gigabyte = 8-gigabyte
Given that
1 gigabyte = 1,024 megabytes
we have to find value of 8 gigabyte in terms of megabytes
for that we multiple both side in above equation by 8
1 *8 gigabyte = 1,024 *8 megabytes
8 gigabyte = 8192 megabytes
Thus, Dijonea have 8192 megabytes on her memory card
they have the same amount of sides as they do angles,
