Answer:

176.71 in^{2}

Step-by-step explanation:

The equation to use to find the radius of a circle is r = \frac{d}{2}

The equation to use to find the area of a circle is A = \pi r^{2}

First, add 3 inches to the diameter of 12 inches. You will get 15 inches.

Second, you will want to find the radius. Substitute 15 for d. Solve to get the radius.

r = \frac{15}{2}

r = 7.5

The radius is 7.5 inches.

Next, you substitute 7.5 for r in the area equation. Solve to get the area.

A = \pi (7.5)^{2}

A = 176.71 in^{2}

Please help me find the area of this shape
natulia [17]

Answer:

62m squared

Step-by-step explanation:

Area= Length x Width. To figure out the area of a strange shape, you should divide it into portions. The top section would be calculated as 4x7=28. The second long and skinny rectangle at the middle is 3x10 (the three being from 7-4 and the 10 from 14-10, both values being the remainder of the space without the first shape), which equals 30. The final shape is the rectangle at the bottom, and to calculate its area the equation would be 1x4=4. You add all these values together (28+30+4) to get 62 metres squared (dont forget the sqaured!).

Mrrafil [7]

Step-by-step explanation:

8 vehicle.

Step-by-step explanation:

Given: Monthly salary of salesperson is $2400

          Incentive of salesperson is $250 per vehicle sold.

∴ Deduct salary from the target amount

\$ 4400-\$ 2400= \$ 2000$4400−$2400=$2000

∴ 2000 need to be earned only through incentive, which is2000needtobeearnedonlythroughincentive,whichis250 per vehicle sold.

Now, solving to get number vehicles to be sold to earn $2000 as incentive.

Number of vehicle= \frac{2000}{250}= 8\ vehicles2502000=8 vehicles

∴ 8 vehicles need to be sold by salesperson to get total earning as $4400
