Claire has a hot tub with a diameter of 7 feet. she wants to purchase a cover to protect the hot tub. what is the area of the cover? use 3.14 and round the answer to the nearest square foot

Answer: area of cover = 38 ft²explanation: the area of the cover would be the same as the area of the bath tub. the bath tub has a circular shape, therefore, we will use the following equation for the area: area =  π  * r²where: r is the radius =    =    = 3.5 ftpi is a constant = 3.14substitute with the givens in the above equation to get the area as follows: area = 3.14 * (3.5)²  = 38.4 which is approximately 38 ft²hope this : )
