Tariq also designs hot tubs. The diameter of the hot tub is 3 meters. What is the area of the deck that surrounds the hot tub? If necessary, round to the nearest tenth. O A.) 3.3 m²
O B.) 7.1 m²
O C.) 17.9 m²
O D.) 18.8 m²

C. 17.9

Step-by-step explanation:

First you have to find the area of the circle, to then subtract it from the area of the square around it.

To get the area of the circle you must take the radius(half of the diameter) and square it. 3^2 is 9. Then you mutiply that by Pi( 3.14). Which is 7.07.

Next you have to subtract that from the area of the square deck.

25-7.07=17.9

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
