Area_{ABCD}=110*140=15400 \ cm^2\\
DO=180-110=70 \ cm \\DF=140-50=90 \ cm \\ Area_{DOF}= \frac{70*90}{2}= 3150 \ cm^2 \\ Area_{ABCO}=15400+3150=18550 \ cm^2

9(b)
Area = (4*6)/2 = 12 

Second picture
Area_{ABCE}=8^2=64 \ ft^2 \\ DE= \sqrt{10^2-8^2}= \sqrt{36}=6 \ ft \\
Area_{ADE}=(6*8)/2=24 \ ft^2 \\ Area_{ABCD}=64+24=88 \ ft^2

Question 1
allochka39001 [22]

Answer:

Step-by-step explanation:

Perimeter of quarter circle = r + r + \frac{1}{4}*2*\pi *r

            = 10 + 10 + \frac{1}{4}*2*3.14*10\\\\= 10 + 10 +  3.14*5\\\\\\= 10 + 10 + 15.70\\\\= 35.70 cm

2) d = 2*10 = 20 cm

Perimeter of semicircle = diameter + (1/2) * circumference of circle

                         = 20 +  \frac{1}{2}* 2*\pi *r\\\\= 20 + \frac{1}{2}*2*3.14*10\\\\= 20 + 3.14*10\\\\= 20 + 31.4\\\\= 51.40 cm

3) Perimeter of three-quarter =  r + r + (3/4)* circumference of circle

          = 10 + 10 + \frac{3}{4}*2*\pi *r\\\\= 10 + 10 + \frac{3}{4} * 2 * 3.14 * 10\\\\= 10 + 10 + 3 * 3.14 * 5\\\\= 10 + 10 + 47.1\\\\= 67.1 cm

If you wanted to use the numeric key pad to divide 100 by 2, you would type _____.
Nookie1986 [14]
If you wanted to use the numeric key pad to divide 100 by 2, you would type D. 100/2. This is because the / sign is used for division on like a calculator or on the web page. It also can stand for a fraction but here it would stand for dividing. 100/2 = 100 ÷ 2.

Johnny invested $1000 in savings account that yields 2% interest annually. How much will Johnny's investment be worth in 10 year
Ann [662]
Calculate the interest in a year
Multiply the annual percentage of interest by the investment to find the interest.
interest in a year = 2% × 1,000
interest in a year = 0.02 × 1,000
interest in a year = 20
The annual interest is $20

Calculate the interest after 10 years
Multiply the annual interest by 10
interest 10 years = 20 × 10
interest 10 years = 200
The sum of interest after 10 years is $200

Find total investment
investment = first investment + interest in 10 years
investment = 1,000 + 200
investment = 1,200

The investment will be worth $1,200 in 10 years
